Reviews:

daytime running light lamp is combined with the dimensions.
The base is a regular 4 pin w21/5w. 21 W – running lights, 5 W – dimensions. It seems like install an LED lamp of that size and that’s it. But no... AvtoVAZ loves to come up with the best schemes and extraordinary solutions. It's the same thing this time. The pinout on a regular base is quite unusual. Therefore, if you install a regular LED lamp , then the following options are likely: either the running light (or dimensions) will not work, or it will start to smoke..

There are several options for solving this problem for us.

Option 3. The most barbaric. Drill out the entire base from the standard Granta connector. Glue the light bulb there tightly and either solder the wires because it is necessary, or purchase an additional connector and solder it to it.

The surest option is the introduction of special non-polar LED lamps . This means that no matter how “+” and “-” are supplied, the electronics inside the lamp will determine how to supply power to the chips.

Rate it! Luminous flux - 720 Lm (halogen close-light lamp gives a flux of 1200 Lm) Chips - South American production CREE, 6 pcs Multi voltage from 12 to 24 V Non-polar Declared service life of more than 30,000 hours.

The photo shows the fuse for daytime running lights on a Lada Granta . When testing and selecting LED lamps, it often burns out.

For comparison. One headlight of the Lada Granta car has an LED DRL , the other has a regular lamp.

And now what it looks like in the darkness. The difference is obvious!

LED running lights and low beams on. Well, in general, the low and high beams also need to be changed to LED lamps. For example, for these – LED CARS H4 HI/LO 3600 LM

Scheme 3

Here, the running lights turn on after the engine starts. The relay, battery and generator are involved. We connect the negative of the DRL to the car body, and the plus to the relay contact marked 30. We connect the relay contact marked 87 to the positive of the battery. We connect the relay contact marked 85 to vehicle ground through the DRL. And with mark 86 we connect to the reed switch, the second contact of which is connected to the plus of the generator. After starting the engine, move the reed switch around the generator so that the relay is activated and the running lights turn on. After this, we pack the reed switch in thermopolymer and attach it to the generator. It is very important that the reed switch is attached exactly in the place of the generator where the relay operates.

DRL Lada Granta

Making DRLs with your own hands for the Lada Granta

Daytime running lights (or DRLs for short) serve to increase the level of safety on the roads during daylight hours. LEDs with good mounting are usually used as light sources for running lights. If the vehicle does not have DRLs provided by the manufacturer, low-beam headlights or fog lights are used. But in this case, the car is the least noticeable, because both of them are configured to illuminate the road surface, and this is a fundamental difference. In addition, low beam and PTF consume more energy, and, as a result, gasoline consumption also increases. Therefore, it makes sense for owners of such cars to think about buying DRLs or creating DRLs with their own hands from LEDs.

Let us consider, as an example, the possibility of installing LED DRLs for a car such as the Lada Granta. The manufacturer provides daytime running lights combined with the dimensions. But in order to save money, Grant received incandescent lamps as a light source. The most common option for upgrading DRLs with your own hands is to purchase conventional LED-based lamps, as in the figure below. With their contacts they are just approaching regular positions.

As practice shows, the only difficulty that Lada Granta owners encounter when installing such lamps is the correct determination of polarity, so the main thing is to correctly install the LED lamp on the Granta.

Oh, this is how Granta looks with LED DRLs.

First you need to decide: how many LEDs to use and what power? There is a 12 V power supply from the battery - which means you can turn on no more than 4 diodes one by one. At a theoretical level, you can turn on several parallel chains of four, but in this case 4 per DRL headlight will be enough (or maybe even 3, if with a good lm/W ratio). To provide the required luminous intensity (according to standards, it must be from 400 to 800 Cd), the power of the LEDs must be approximately 1...1.2 W.

It is recommended to purchase LEDs from one of the recognized manufacturers, already mounted on an aluminum board. For example, DRLs on Gree LEDs (XP series or the most economical XTE, XBD series are suitable), OSRAM (Oslon series), you can also pay attention to LEDs from Korean manufacturers, they are usually cheaper than Samsung and Seoul Semiconductor series similar in features indicated above.

The diodes must certainly be on a duralumin board, because They are not adapted for manual installation and it will not be possible to install them with your own hands without damaging them. LEDs from an unknown Chinese manufacturer may turn out to be half the cost, but they will almost certainly shine twice as bad, so it’s not worth the risk.

Next you need to take care of the secondary optics, which should be selected in accordance with the type of LED. The angle should be about 20˚ in the vertical plane and about 40˚ in the horizontal. A more suitable lens for the XPE LED is CA11052_TINA2-O (LEDIL).

The next step is manufacturing the radiator housing.

You can create it with your own hands either from a ribbed radiator profile or from a regular U-shaped one. In the 2nd case, the overall dimensions will be larger, but the filling (LED module with lenses) can be recessed inside. In our case, the area of the diffused surface must be at least 100 cm 2, and certain profile dimensions will depend on the installation location of the headlight, the size of the LED modules and lenses.

It is better to secure the LED module on the radiator with screws or rivets, because Thermally conductive adhesive may not withstand such formidable implementation criteria and there is a risk of losing the LEDs somewhere along the way. The lenses are attached using holders that come with them and have double-sided tape on the base. Because of the reasons indicated above, it is recommended that after installing the lenses, additionally secure them with transparent silicone sealant, covering the perimeter. It’s better to fill the entire module with sealant, so that only the lenses above the surface remain, then you don’t need to solve anything else for moisture protection and there will be no need for protective glass. The main thing is not to forget to remove the power wires.

We come up with a method for attaching the running lights to the car - here are ready-made DRLs made from LEDs with your own hands!

It is imperative to connect the headlight to the power supply through a limiting resistor, the value of which will first need to be calculated at a theoretical level, and then actually checked.

If the voltage on a charged battery is 12.6 V, the voltage drop across one LED (according to the manufacturer) is 3 V, then to ensure one-watt mode you will need a resistor with a nominal value of 1.5 Ohms and a power of at least 2 W.

You can connect the DRL to the car’s network using different methods, depending on the required method of operation and the brand of the machine. In any case, you can create all this with your own hands using the diagram.

Connecting DRL from the handbrake of Lada Granta (photo guide)

I have long wanted to create DRLs from the handbrake on Grant. I took relevant information on connection from various sources, including on the Lada Granta forum. On the Granta in the Norma configuration, the DRLs light up from the ignition. At the moment, when the handbrake is raised, the DRLs do not light up; when the handbrake is lowered, the DRLs light up. I took a socket for a relay with mounting in a mounting block 10r, a regular 5-pin NC (Normally Closed) relay 50r, wires, auto blade terminals (socket/mother), 3 diodes FR207 - Pulse diode 2A 1000V 1.70r for 1 piece (instead of a diode FR207 you can use a 1N4007 1A 1000V diode, but the 1N4007 has a narrow leg and bends), a soldering iron, heat shrink, and electrical tape.

Switching on through dimensions or low beam

The second version of the DRL connection diagram involves using the power circuit of the side light bulb. To do this, the positive wire from the running lights is directly connected to the “+” from the battery. In turn, the negative wire is connected to the “+” of the side light, which is currently electrically neutral. As a result, the following current flow path is formed: from the “+” of the battery through the LEDs to the size, and then through the light bulb to the body, which serves as the minus of the entire circuit. Due to the low current consumption (tens of mA), the LEDs begin to glow, and the lamp spiral remains extinguished. If the driver turns on the side lights, then +12 V appears on the positive side of the side lights, the potentials on the DRL wires are equalized and the LEDs go out. The circuit goes into normal mode, that is, current flows through the side light bulbs.

This circuit solution has several disadvantages:

running lights remain on when the engine is turned off, which is contrary to current regulations;
the circuit will not work if LEDs are also installed in the dimensions;
the circuit will not work correctly if the DRLs contain powerful SMD LEDs, the rated current of which is comparable to the current of a light bulb;
For safety reasons, an additional fuse must be installed.

Selection of LED lamps for DRL Lada Granta

Car : Lada Granta. Asks : Maxim Rastyagaev. Question : I would like to install LED lights in the DRLs on the Lada Granta, is it worth it?

I bought LED lights in the DRL on Granta from the store. The merchant said that a lot of people do exactly this.

Pros of DRL:

The diode has a longer service life
brightness and visibility are better.

In general, there are only advantages. But when I left the store, one guy said that there was probably an error that would be displayed on the device panel. Because the car will think that the filament is faulty, because the diode consumes less electrical energy. Is this so, and is the game worth the candle? I can still return the lamps to the store, I haven’t opened the packaging.

Additional indicators on the panel

The LCD display on the panel displays information from the on-board computer. The open door indicator glows red if one of the doors is not closed. The low fuel indicator indicates the need to refuel (ignoring this signal may lead to failure of the fuel pump).

The weak tire indicator illuminates when tire pressure is low. If the driver is not wearing a seat belt, the seat belt sensor lights up. The airbag status indicator lights up in cases of system malfunction; you must contact a service station, since the airbag may inflate randomly. If any indicator fails, you can ring the system and find the reason; the pinout of the instrument panel will help with this.

LEDs in DRLs on Lada Granta, not everything is so simple

For us, this article would be perfectly suited to a picture with a demotivator: it is not allowed to just take and install LED lights instead of ordinary daytime running light lamps.

Types of DRL lamps

It all depends on what kind of LEDs you got! There are two options.

SRCK pinout.

Scheme 4

This option is a variation of the previous scheme when a reed switch is not available. Then the contact marked 86 is attached to the oil pressure lamp in the dashboard. In this case, the lights will also turn on after the engine starts. This option is done with your own hands somewhat easier than the previous one.

How to properly connect daytime running lights

conclusions

Regular DRL bulbs are very good.

They shine great, the diodes shine better, but no one has used DRLs before. This is all marketing needed in order to equip the card with additional elements for which you will need to pay. Replacing a DRL lamp is ordinary; an ordinary lamp costs about 100 rubles, while diode lights will cost you several times more!

I would think about substitution only if I had problems with conventional equipment!

For me, the most important advantage of an LED lamp is that if one diode burns out, the other diodes will continue to work. In other words, you can keep moving!

Naturally, installing LED lamps is a step forward for your car. But you need to think about the other drivers. If you install it, you need to immediately adjust the direction of the light so as not to blind oncoming people.

I made myself a backlight from LED lamps in the cabin. Now the crotch between the seats and the pedals are illuminated. I was very pleased, because at night, the interior is lit no worse than during the day, as needed. It gives an error on the device panel, but everything has been fine for more than one year.

I thought for a long time about installing LED lamps, but when I finally decided to do it, I was pleased. The panel did not give me any errors, and they shine even better.

I installed the running lights following your instructions, connecting them to the headlights button. The “dimension malfunction” light is on. The shine is unsurpassed! The car began to attract more attention.

You need to add additional resistance, the machine thinks that the lamps have burned out. Although surprisingly, I didn’t have one!

hi, I tried to install LED lamps on the DRLs, the fuses popped up, sorry about that

Marvelous. Diode lamps consume less and do not have to be. Bad advice - but try the other lamps.

the polarity does not match, look where + and where -

This is literally due to polarity, I had this happen, the fuses were blown, until the store checked the lamps, the jamb was in them

Chinese lamps, take them back to the store. Closing only from them

What additions don’t even need to be created and everything doesn’t show any errors, it’s just that they’ve read all sorts of nonsense and are discussing and messing with people’s heads

Look for lamps with non-standard polarity and everything will be fine

I ALSO BUYED FOR 750 AND I DON’T REGRET, I ALSO WAS AFRAID OF WHAT WOULD HAPPEN AND IT TURNS OUT EVERYTHING SIMPLE

Of course they ate to take it for 200-250 rubles. There will be no use there

Replacing Lada Granta DRL lamps: how to get everything right

The Lada Granta DRL lamp is a lighting device for daytime running lights. In cars of this brand for us, the function of such lights is performed by dimensional lamps. In the technical literature they are called that: double-filament lamps for side lights and daytime running lights (DRL). When the ignition is turned on, a 21-watt thread of running lights lights up, and when the headlights are turned on, a 5-watt thread of side lights lights up.

The manufacturer equips the Lada Granta with the most ordinary and cheap DRL lamps. They have many disadvantages, but only one advantage - low cost. Some of the main consumer complaints about these lamps are dim yellow light and a very short service life.

Car enthusiasts who do not want to put up with the shortcomings of conventional daytime running lights replace them with other models at the first opportunity. LED lamps without a base assembly or lamps with increased visual comfort are suitable as light sources. The range of such lamps is quite wide; you can find them in virtually any auto parts store. When choosing LED lighting sources, experts advise using the brightness parameter.

Scheme 1

The first option involves automatically turning on the DRL after the ignition starts and turning it off after stopping the engine. The minus is connected to the car body, and the plus is connected to the plus of the ignition switch. All this is quite easy to do with your own hands, even without special knowledge in the field of electrical engineering. The main thing is to carefully monitor what is connected where.

Diagram of automatic activation of daytime running lights

High visual comfort lamps

The Lada Granta DRL lamp of high comfort is a simple halogen incandescent lamp of close light, shining snow-white. The main drawback is poor visibility in rainy weather due to the fact that snow-white light produces much more glare from wet surfaces and raindrops than yellowish light.

The following brands of halogen lamps of the highest convenience are more often found on sale: OSRAM, General Electric, Mayak, Philips, Narva, IPF, Hella, etc. The manufacturer advises choosing OSRAM H4 models in Standard and Light Day modifications. The first one fully complies with all norms and legal requirements regarding safety, illumination, geometry and accuracy of the cut-off line. Has the highest luminous intensity. The 2nd model differs from the first significantly in its longer service life. In terms of luminous intensity it is slightly inferior to the Standard modification.

Changing low beam lamps is done as follows. Free up access to the left headlight unit. To do this, release the Lada air filter housing from all fastenings, disconnect the wiring harness and sensor. Then slide the filter housing up and to the left. To gain access to the right headlight unit, you need to remove the unit cover. To do this, unscrew the oil filler cap, and then the 4 mounting bolts. After this, pull the cover up and snap it off.

To remove an old lamp, first turn the socket counterclockwise, then carefully pull out the light source. Install the newest one in reverse order: first install the base into the groove of the cartridge, then screw the cartridge clockwise.

Please note: when changing halogen lamps, it is not recommended to touch the test tubes with your fingers.

The fact is that fingerprints on the bulbs of light devices repeatedly reduce their service life. Therefore, you need to work in clean cotton gloves without rubber coating. Wipe the tubes themselves with alcohol wipes before installation.

Replacement instructions

To gain free access to the left block, move the housing that covers the air filter and protects it from external factors. To do this, you will need to remove all the harnesses and housings from the device, and then simply move the desired housing up.

With the right block the situation is somewhat different. In this case, to replace the running lights on the Lada Granta, you will need to dismantle the power unit cover. To do this, first remove the cover of the oil filler system, after which the desired housing is snapped off. It is worth noting that the cover can be firmly fixed, so you should firmly pull up to remove it. After replacing the running lights, be sure to return the cover to its installation location to avoid the risk of any hard dirt or debris that accumulates under the hood getting into the neck.

Aspects of installing LED DRL lamps

If there are no baseless LED lamps for the Lada Grant, you can install simple base ones. In this case, you will have to remove the base from the diode without the help of others, and fit the free antennae to the mounting holes.

After replacing lamps, do not throw away old halogen devices. The fact is that in order to comply with regulatory and technical requirements for daylight, after installing the latest lamps, you will need to visit a technical center. Otherwise, the next scheduled technical inspection will prohibit the operation of the car with such modified lights.

There are a huge number of LED light sources available in different colors and colors. But according to standards, the light emitted by daytime running lights should only be snow-white or yellowish. All other colors are prohibited.

LED lamps consume significantly less electricity than conventional incandescent lamps. Therefore, installing LED lights will significantly reduce the load on the battery. If you forget to turn it off at night (that is, in the dark)

running lights, the battery will practically not be discharged by morning.

The design of the Lada Granta car provides a relay that monitors the serviceability of the DRL. In addition, this relay immediately monitors the functioning of the injector and brake lights. Considering that LED lamps consume less energy, the monitoring relay may give incorrect readings, indicating that the running lights are faulty. In other words, the DRL lamp on the dashboard will often turn on, and the on-board diagnostic system will constantly beep.

To get rid of a similar problem, you need to replace the regular dashboard with its export version, created for the European versions of the Lada Granta.

Necessary materials

Before connecting daytime running lights to your car, you will need to stock up on all the necessary tools and materials. To do the job yourself, you will need:

pliers;
wire cutters;
soldering iron;
insulated two-core wire;
LED DRLs;
relay for cars 12V;
reed switch;
single-core wire;
plastic clamps.

Once everything you need is in stock, you can begin connecting the DRLs to your car with your own hands.

How to change running lights on a Lada Granta

On the Lada Granta, the dimensions are combined with daytime running lights in one lamp. During the ignition, the DRLs are turned on, and when the headlights are turned on, they go out and the side lights turn on. The main advantage of light sources is their efficiency, compared with close-up lighting lamps, and also the lowest fuel consumption.

DRLs should not be confused with side lighting. It is even the least noticeable and indicates the size of the car when it is parked at night. If we associate this light with other methods of lighting a car, then it is more harmless (has no glare, is equipped with sufficient brightness) and consumes a small amount of fuel.

The factory equipment provides for the presence of the most common incandescent lamps in the Lada Grant. Their properties are well known to car enthusiasts - the light in the lamps glows dimly, with a yellowish tint, and they have a short service life. For this and other reasons, car enthusiasts sometimes need to replace lights.

The properties of external light sources are established by Russian legislation. To drive safely on Russian roads without breaking laws, you must:

place the light bulbs on the body of the Lada Granta in front at a height of 25 to 150 cm from the ground;
maintain a small distance between the bulbs (60 cm);
take products with an area from 40 to 200 cm 2.

Lamps used on the Lada Granta

Scheme 2

The second option is, in fact, a variation of the first. The same operations are performed here with one small difference - after turning on the low beam headlights, the running lights turn off. Here the plus is connected, as in the previous section, and the minus is connected to the plus of the low beam lights.

This is explained by the fact that the incandescent lamp, which is used for low beam, has a lower resistance and a higher current flows through it. The moment the low beam turns on, a plus appears on the negative side of the DRLs and they go out.

This option is also quite easy to implement with your own hands - it is important not to confuse and connect all the contacts correctly.

If you have incandescent lamps installed as dimensions, you can use this principle for dimensions.

Types and causes of failure

These devices have several types:

low beam headlights. Turned on during vehicle operation. In Russia it is allowed to use them as a light source for daytime driving;
high beam headlights. Operate at reduced voltage. This helps to reduce the intensity of light, which in some cases does not help increase the visibility of pedestrians and cyclists on the road;
fog lights. Their implementation in the Russian Federation is permitted (clause 19.4 of the traffic rules);
front turn signals;
individual light sources in front of the vehicle with specific light intensity patterns.

Headlight Lada Granta with LED lamps

The main manufacturers of high-quality DRLs are brands such as:

These and other models of light sources may differ in shape (rectangular, round, oval), the number of diode bulbs inside, power, and brightness.

Now manufacturers have even begun to produce silicone diode bulbs suitable for the Lada Granta. They can be placed on one or several tapes.

Among the main reasons why DRLs do not glow are:

lack of polarity check before installing light sources;
the turn signal channel does not light up;
fuse is blown;
lack of heating or burnout of the filament.

In order to improve daytime running light sources and make them as useful and elegant as possible for the car enthusiast, all stages of the work must be done very carefully. Instead of conventional lamps, which do not glow very brightly, you can install LED lighting without a base assembly. You can purchase these components in virtually any store that has spare parts for cars. With all this, when making a choice, you need to focus on models with greater lighting brightness.

Operation of LED lamps

Maintenance Tips

As you know, even the most minor breakdown, if not repaired in time, can result in serious problems. Therefore, you need to follow these simple recommendations to extend the life of your machine by years:

perform regular inspections as often as possible; monitor the condition of the devices installed on it; use only high-quality components; eliminate breakdowns as carefully as possible.

It should always be securely fixed in the holders and not dangle.

A problem with light is indicated by:

uncharacteristic crackling sound when turning on the headlights;
loud relay clicks;
button failure;
Steering column switch failure.

Here you need to deal with the problem as soon as possible, before the external lighting fails completely. If the headlight glazing is damaged, it must be replaced. Otherwise, moisture will quickly seep inside and the contacts will oxidize.

When purchasing new lamps, it is important to remember a few simple truths:

those that are too powerful shine a little brighter, but increase the load on the electrical circuits;
cheap ones quickly burn out - frequent replacement leads to increased costs.

When doing repairs yourself, it is important to always ensure that you do not damage the connecting terminals or the wires themselves. If one of them breaks, it is worth replacing it completely - electrical tape or twisting will never be a worthy alternative

If a lot of such weak points accumulate, then in the end:

the wiring resistance and, accordingly, the load will increase;
short circuits and often fire may occur;
The fuses will always be on.

Installing the latest lighting

The required increase in brightness or service life of light bulbs can be achieved only by replacing working lights. Car enthusiasts often replace the halogen lighting sources installed in Lada with LED ones. Usually, even a person without experience in changing lamps can cope with this task for us. But there are several aspects you need to know. Simply putting the latest LED in the required space is not enough - the process has its own characteristics. They are:

it is often necessary to tear off the previous base from the diode in order to move its parts to the required holes;
the driver will definitely have to check the polarity of the light sources on the Grant to ensure the safety of the fuse. If this is not done, the fuse that controls the voltage in the network will simply blow out. The fuse, which is installed in this car model for us, is capable of de-energizing the non-hazardous operation of the electronic circuit.

Before changing light bulbs, you must make sure that such a procedure will not violate current legislation.

You must also remember to undergo routine inspection. It will help determine whether the shift procedure is unsafe. Having taken out an old light source, do not immediately throw it away. If you don't pass inspection with your new bulbs, it might be wise to return the old ones to their space. Also remember that the legislation of the Russian Federation allows only snow-white and yellowish lighting on cars - other colors are outlawed.

Changing the lighting on the Lada Grant to LEDs, which are very popular in recent times, provides many advantages:

consumption of the least amount of electricity and, consequently, fuel;
the longest operational life (some are designed for the entire life of the Lada Granta);
good visual effects, colorful lighting of the road surface;
These models do not put a huge load on the generator or overload the fuse.

Installation Requirements

The key disadvantage of running lights is that current regulations do not consider them as standard lighting. In this regard, you may encounter various problems when interacting with authorities. Special lighting must fully comply with the standards established by current legislation. In this regard, when replacing running lights with your own hands, you need to make sure that the new lamps for the Lada Granta comply with these standards.

Types of DRL lamps

In the usual version, DRLs for the Lada Granta are equipped with standard 21-watt incandescent lamps. Their only advantage is their low cost. But the price for this is insufficient brightness of the luminous flux (which is especially important in bad weather) and a short service life. Considering that the procedure for replacing daytime running lights is quite labor-intensive work, then it is better to immediately install conventional lighting devices that are durable and have good lighting performance.

Among other DRL bulbs, two main options can be distinguished:

Halogen, belonging to the group of high visual comfort due to radiation in the snow-white spectrum of the light range.
LED, characterized by low energy consumption and the highest brightness.

Fundamentally! When choosing lamps to replace in the navigation light system on a Lada Granta, in order to avoid conflict with inspectors, special attention must be paid to the compliance of their lighting characteristics with the law. For example, LED elements with snow-white light are capable of producing different blue-violet colors under different circumstances (wet headlight glass, individual reflector), which, based on the beliefs of traffic regulations, is unacceptable.

Common DRL faults

Most often, the running light bulbs in the Lada Granta burn out due to various mistakes being made during the process of replacing them. First of all, you need to remember that when replacing, it is strictly forbidden to touch the flasks with your fingers. In this regard, before carrying out work, you should acquire cotton gloves that do not have rubber coating. Leaving greasy fingerprints on the bulb will significantly reduce its service life. In order to remove all dirt, you should carefully wipe the flask with a napkin pre-treated with alcohol.

High visual comfort lamps

Although the standard lamps with a dull yellow color in the running light system may still remain fully operational, almost all Lada Granta owners strive to immediately replace them with halogen ones with a catchy snow-white light. The reason for this is an increase in visual comfort. It is also noted that this can highlight the exterior profile of the car.

Halogen light bulbs from the following manufacturers are most popular among car enthusiasts:

Philips.
Lighthouse.
OSRAM.
IPF.
General Electric and some others.

Like other modifications, halogen lamps for DRLs have the same corresponding number of shortcomings. This is primarily due to increased heating and, as a result, the shelf life decreases with increasing power. For this reason, when choosing similar sources for the Lada Limonka, you should take into account that they can be produced in 2 versions:

Option 1 meets all legal requirements, but at the same time has average durability. The 2nd is the most economical and, although it does not shine as brightly, it lasts longer.

Pay attention! The grease mark left on the surface of the test tube when replacing it can significantly reduce the service life of a halogen lamp. Therefore, when reinstalling, it is imperative to wear cotton gloves, and after installation, wipe the surface of its glass with clean alcohol wipes (if contamination has been applied).

About lamps with increased visual comfort

In Lada Granta, standard devices are halogen, but at the same time they have a rather pleasant light spectrum.

When it rains, visibility is significantly reduced due to the fact that white light produces strong glare from any wet surfaces compared to the yellow tint that many are accustomed to.

In the production of Lada Granta, two versions of such headlights can be used. The first fully complies with the recommendations specified in the current legislation regulating driving safety, including the parameters of the cut-off line, power, radiation geometry and other characteristics. The second is more durable, but its power is less.

LED running lights

The main advantage of using LED elements when replacing running light bulbs on a Lada Granta is their low energy consumption with the highest luminous power. When installed correctly, they do not heat up, last an order of magnitude longer than standard ones and do not overload the on-board network, extending the battery life.

There are two types of LEDs for DRLs:

SRCK.
Convntional.

The 1st option has the correct pinout of the plus and minus (in height), the 2nd option is poorly suited for the running lights of the Lada Granta and will require modifications to the base, separate wiring and other actions. This must be taken into account when searching for a replacement lamp.

Fundamentally! LED lamps usually include several LED elements. Therefore, when one of them burns out (several at once never deteriorate), the headlights will not stop shining and movement along the road can be continued without violating the rules.

The process of replacing DRL lamps

In order to correctly replace the lamps for the running lights of the Lada Grant, you need to take into account not only technical, but also legal requirements.

Installation Requirements

A common drawback of DRLs is the fact that they are not described in the law as a single vehicle lighting device. Against this background, various frictions may arise between car owners and inspectors. But there are a number of regulatory requirements according to which they are met and installed. So, in order to change the running light bulbs, you must comply with the following technical conditions:

The placement space is only in front of the car.
The height from the road surface is from 0.25 to 1.5 meters.
The distance between the internal parts of the headlights is at least 60 cm.
The area of the luminous surface must fall within the range of 40 to 200 cm 3 .

The power of the running lights must be sufficient so that the dimensions of the vehicle are visible from a distance of at least 200 meters.

Step-by-step instruction}

The procedure for replacing running light bulbs on a Lada Granta comes down to the following main steps:

Turn off the ignition system, disconnect the on-board power supply, disconnecting the battery terminals.
To change the light bulb in the right headlight, you need to remove the decorative engine cover and unscrew the oil filler plug.
Having reached the running light bulb, you need to turn its socket counterclockwise and remove it by pulling it towards you.
Install a new car light bulb, performing all steps in reverse order.

Fundamentally! If you need to create a replacement on the left side of the optics of the Lada Grant, you must first remove the air filter housing, also disconnecting the sensor and all conductors and pipes suitable for it.

Individual installation of LED DRLs

Installing LED lamps in running lights has many advantages. But along with this, their substitution is associated with a number of features that simply cannot be ignored:

It is necessary to install LED elements on both headlights of the Lada Granta at once.
It is necessary to check the polarity using a tester, without which, when turned on, the LEDs will immediately burn out and the fuse will deteriorate.
Not all diode lighting devices fit into standard sockets right away - you often have to open the base to connect the contacts.

Pay attention! Replacing the standard lamps in the running lights with LEDs in the Lada Granta, due to the low power consumption of the latter, will trigger the “DRL malfunction” light on the panel unit. In some cases, a sound signal may even sound. Installing a European version of the dashboard will help solve the problem.

Scheme options

So, you can connect in several ways.

The DRL turns on as soon as the ignition key is turned. The lights do not go out until the car engine stops. It is considered the simplest method, which does not involve the use of an on-board network. It is enough just to connect the negative from the lights to any place in the car body, and connect the positive from the lock to the output of the high-voltage module, always through a fuse.
The same scheme, only the DRLs go out immediately as soon as the low beam is turned on. To implement this connection option, you need to adhere to the diagram described above, with the only difference being that the negative is connected to one of the positive wires of the low beam lamp. As soon as the low beam on the car is turned on, a positive impulse will appear on the minus DRL and the lights will go out. The DRLs will light up again as soon as the high beams are activated or the headlights are turned off.
Connection diagram, which involves automatic connection of the DRL as soon as the car engine starts. It is considered the most reliable option for self-integrating LED daytime running lights. To implement this scheme, the minus of the DRL is connected to the car body, and the plus is connected to the relay contact.

Simple circuit with 4-pin relay

There is a simplicity in circuit number 1, implemented through a 4-pin relay. However, this option does not always satisfy the requirements of GOST, since the DRLs will shine separately from the head optics. The lights are not turned off by a push-button mechanism, everything happens automatically.

The photo above shows exactly this circuit, connected via a 4-pin relay. It implies the following procedure:

when the engine starts, an impulse is sent from the generator to the relay, and the LEDs light up;
As soon as the headlights are turned on, the DRLs turn off.

This connection method is also possible without using a generator. Then, instead, the voltage source will be the battery, the positive of which should be connected to the 30th contact in the photo.

It is also possible to connect the plus from the parking brake. In this case, as soon as the handbrake is activated, the daytime lights will go out - that's the button.

Circuit with 5-pin relay

It involves the use of 4 contacts. Ideal connection option for Priora cars. The difference from the above diagram is not only in the number of relay contacts. This circuit does not provide for the use of output 87. An alternative to ground is output 86.

The circuit with a 5-pin relay provides for the use of DRL control. The push-button mechanism is built between the generator and the 30th relay contact.

The operation of the DRL is as follows:

the internal combustion engine is started, thereby the impulse from the generator goes to the 30th contact of the relay, and from there to the plus of the DRL;
the lights come on, the minus is connected to any part of the car body;
when the dimensions are used, the coil is activated, the 30th contact is integrated with the 87th, the pulse no longer arrives - the DRL is turned off.

With reed switch

In a circuit using a reed switch, three important automotive systems are simultaneously activated: the generator, battery and relay.

The photo above shows a detailed connection diagram for the option using a generator. The plus is integrated, as can be seen from the diagram with point 30. The relay contact, marked with point 87, is integrated with the battery positive. Another relay contact, marked with number 85, is connected to the vehicle ground through the DRL.

Attention. This scheme implies the mandatory use of a reed switch - a device capable of changing the state of a connected electrical circuit when exposed to a magnetic field.

The contact marked on the diagram with point 86 is connected to the reed switch. From the reed switch there is a connection to the plus of the generator.

Thus, the scheme implies the following. As soon as the internal combustion engine starts, the driver activates the reed switch with a button, the relay is activated, and the DRL turns on. The reed switch must be packed in thermopolymer and securely fixed to the generator.

Advice. It is important that the reed switch is fixed exactly in the place of the generator where the relay would operate.

Without reed switch

A variation of circuit number 3, only without using a reed switch. In this case, the contact marked 86 is integrated with the oil pressure lamp in the instrument panel. Thus, the option of turning on the DRL after the engine is started is supported.

It is noteworthy that this scheme is much easier to implement with your own hands than the option with a reed switch.

Video: how to connect DRL from a generator

As you can see, connecting the DRL to the vehicle’s on-board network is carried out using several circuits. The plus is taken from the output of the generator, less often from the battery.

Main conclusions

As standard, the Lada Granta car is equipped with low-power incandescent light bulbs in the running light system, which are not distinguished by good brightness and durability. Their replacement is likely with subsequent other light sources:

The first ones belong to the group of high visual comfort, have good brightness and speed of installation. But during installation, they can simply be damaged by putting a grease mark on the surface of the test tube, not to mention that the stronger they are, the less they serve. LEDs do not have such disadvantages, consume less energy, save battery resources and are very durable. Their main drawback is the formation of blue reflections and the originality of the base, which complicates the replacement function. In addition, LED bulbs can trigger sensors on the dashboard.
