Dashboard lighting for VAZ 2107: what lamps are needed and how to replace them

If the instrument panel on a VAZ 2107 does not light up, then this does not have a negative impact on the operation of the car during daylight hours. However, very strong inconveniences arise at dusk. It is very difficult to drive a car at night if the dashboard lights are not working. We will consider in detail what could be the reasons for the malfunction of the instrument lighting on a VAZ 2107 car, as well as ways to eliminate them.

Why do you need additional lighting?

Today, car tuning is carried out not only outside, but also inside its interior, and there is no better place than the dashboard. Diodes built into the panel will allow you to achieve the following positive aspects:

give the dashboard a new unusual look;
High-quality illumination of important elements of the dashboard;
make additional lighting for the vehicle interior;
make your car ride more comfortable;
improve road safety. When the instrument panel is well lit, all the indicators are clearly visible on it, which allows you to correctly assess the position of the car on the road and not violate the rules of the road with your driving.

The easiest way to illuminate such an element of a car as the dashboard is to install diodes in it. The following types of LED products can be used here:

separate diodes. Using them as backlight, you can create full or decorative lighting for the dashboard. It is worth noting that LEDs can glow in different colors. Therefore, such LED lighting can beautifully complement external tuning, glowing with it in the same color scheme;

LED Strip Light. This tape is very often used as decorative lighting not only for a car, but also for home premises or street elements. It can be easily replaced with another, which will allow you to change the boring color scheme to a new one. The LED strip has a self-adhesive base, with the help of which its installation by hand is quite easy and quite quick.

Why is it necessary to change the backlight bulbs?

When driving in conditions when it is night outside, the headlight light reflected from the ground has a small blinding effect on the driver, who does not see the readings taken from many of the car’s instruments. These may be: speedometer, tachometer, etc. In addition, various buttons on the instrument panel and levers designed to control the heater air damper become invisible.

Trying to find all these devices and use them in the dark can be quite a dangerous undertaking. This is due to the fact that the driver is distracted for a very long time in order to find this or that button, or to determine, for example, a parameter such as speed.

Malfunction of lamps, as well as their absence, disrupts the overall illumination of the dashboard and complicates the process of driving a car at night. That is why it is important to promptly change burnt-out lamps and monitor their condition. Let's try to figure out how to replace backlight bulbs on various VAZ cars.

What lamps to install in the instrument panel for lighting

On the VAZ 2107 car, simple incandescent light bulbs with a tungsten spiral are used for instrument lighting and display. With the development of industry, LED lamps of suitable sizes began to be produced. Despite the fact that they are more expensive, they began to replace incandescent lamps.

cleaner light;
less power consumption;
durability.

Incandescent lamps

AMN 12-3-1 lamps are installed to illuminate the instrument panel.

Brand A 12-1.2 lamps are installed as signal lamps.

LED bulbs

As mentioned above, LED bulbs have a number of advantages over incandescent bulbs, so you should consider changing them. Selecting the size and power of lighting is quite simple.

You just need to take into account that the battery charging indicator lamp must be connected to the nominal resistance of the incandescent lamp previously installed. Otherwise the control will not be correct. Types of light bulbs for illumination and indication are shown in the photo below.

Replacing the backlight

To improve the quality of your dashboard lighting, it is advisable to install new LEDs in place of the old ones. They provide excellent illumination, consume minimal energy, and guarantee a high level of data reading.

Buy a set of LED lamps, having previously calculated the number of devices needed for each sensor.
After removing the block, install the resistors and lamps in specially designated places on the VAZ 2114 - in the sockets. To dismantle the cartridges, they are carefully unscrewed counterclockwise. New sockets are installed in their place and light bulbs are inserted. Respect the polarity and position the LED heads. They will have to be carefully ground off.
Connect the power and check how the new backlight works.
Reassemble step by step. Be sure to route the wiring to the board and carefully secure it to it. This way, the backlight components will not interfere with the reassembly process.
Make sure the instrument panel arrows are positioned correctly. When trying to quickly complete a job, they often become deformed and bent.
The backlight structure is fixed with screws.
The power for the LEDs is connected to the power supply for the light bulbs, the arrows are put on and set to zero.
Using the on-board computer, check the operation of each sensor and device. If the IDs are functioning correctly, return the instrument panel to its original condition. That is, assemble the entire assembly.

Replacing warning lamps and backlight lamps

First you need to determine exactly which light bulbs need to be replaced. Next, in order not to damage the panel when changing lamps, it must be placed face down on something soft, as shown in the photo at the beginning of the article.

We take the socket in which it is necessary to change the light bulb with two fingers. With a slight movement, turn it counterclockwise and remove it from the electronic board.

If new light bulbs were purchased together with a socket, then carefully insert them into the board together with the socket, turning them all the way.

If the light bulbs were purchased without a socket, then remove the burnt out bulb from the socket, insert a new one and return the socket to its place on the board.

Carry out this operation with all burnt out bulbs.

After replacing the light bulbs, you need to assemble the instrument panel and install it in place. All assembly and installation operations are done in reverse order.

Replacing dashboard lamps yourself

When the panel lamps stop lighting, you should immediately replace them with new ones. For this job we will need the following arsenal:

Let's get started

First of all, we remove the decorative trim of the radio (since the dashboard and radio are connected to each other, you will have to disturb the music system too), which is held on by fasteners; here it is better to use a screwdriver, threading it under the trim.

The main condition of work is caution. You need to start detaching the cover from the bottom edge

When the bottom edge comes off, you need to pull it towards you a little. Now detach the top edge. Further:

Disconnect the wire directed to the cigarette lighter.
In the same way as we removed the cover from the radio, we remove it from the dashboard. Above the left and right edges we find two self-tapping screws. They need to be unscrewed. We unscrew the screws located at the top and bottom.
We remove the trim with a little effort (since it is also held on by fasteners, so the decorative plate will have to be rocked a little).
We disconnect all the wires: from the alarm system, from the clock, from the headlights and other things.
We remove the control panel itself, for which we unscrew the four screws on which it is held. In order not to damage the wires, it would be better to disconnect them on the one hand.
Now the most important thing. We remove the sockets of the light bulbs that have stopped burning. To remove the cartridges, you need to turn them counterclockwise with a gentle movement. We replace the defective lamps with new ones, wrap them and install the entire structure in the reverse order of disassembly.

Removing the instrument panel and preparing for replacement

To change the lamps in the instrument panel, the latter will have to be removed. It cannot be said that the PP can be removed with one movement of the hand: the designers of the VAZ 2107 made dismantling a little more difficult than on other cars of the VAZ family. Nevertheless, dismantling the PP is quite feasible in a garage or even a parking lot. In this case, the operation does not require any special knowledge. The tools we will need are:

small flat screwdriver or knife;
crosshead screwdriver.

I think all this will be found in the trunk of any VAZ 2107, and we can get started. First of all, we remove the plastic handles from the heating control knobs by prying them off with a flat screwdriver.

Removing handles from the seven's interior heating system

We unscrew the nut securing the daily counter reset button (marked with a red arrow), and push the button itself inside the shield.

Removing the daily counter reset button

Now you need to unscrew the screw that is located under the plug and secures the decorative trim. Remove the plug using a flat-head screwdriver and unscrew the Phillips screw.

Removing the fixing screw of the PP decorative trim

After this operation, the right side of the panel will move away so that you can get to the flexible speedometer control shaft.

Releasing the right side of the control panel on a VAZ 2107

The shaft is removed with bare hands: simply unscrew the nut securing it.

Removing the speedometer drive

Now remove the instrument panel from the clamp that secures its left side and pull it out slightly to get to the vacuum hose connected to the econometer. It can also be removed with bare hands, but be careful not to tear it.

Removing the vacuum hose from the econometer to the PP

It remains to disconnect the three power connectors of the instrument panel and the three wires on the VAZ 2107 heater switch. Before disconnecting, it is advisable to mark them so as not to confuse them when assembling the panel.

Disconnecting the power wires from the heater switch

We remove the decorative trim along with the PP and unscrew the four self-tapping screws securing the shelves (two on each, I marked them with red arrows) to the decorative trim, and the instrument panel can be removed.

Block lights

Here are the turn signal bulbs, dimensions, low and high beams. To get to the side lights and low and high beam lamps, you need to:

Remove the protective cap. We turn it counterclockwise, the indicators are marked on it. It has no thread, but can be removed by turning it 180 degrees. In its inner part there are “antennae” with which it is fixed in the body of the headlight unit.

Remove the wire retainer. It secures the low beam lamps in the reflector housing. This clamp is made of elastic metal, so you need to remove it carefully. We take its upper ends out of the grooves and lower them down, freeing the socket of the high and low beam bulbs.

We take the lamp out of the reflector, holding it by the base, and remove the plug.

Changing the headlight bulb

We take it out of the reflector housing along with the socket. If you haven't done this for a long time, then getting it out will be problematic. To do this, remove the low and high beam unit. We insert a finger into the reflector hole, feel for the size bulb and push it out with a little force.

To replace, you need to lightly press the light bulb and turn it half a turn. It will come out of the plinth retainers and can be easily removed. We insert the new one in reverse order.

Direction indicators

We turn the turn signal socket counterclockwise half a turn in the headlight unit housing.

Let's take it out. The lamp, similar to its dimensions, is fixed in the socket with two “antennae”. Therefore, they pressed lightly on it, turned it and took it out. The cartridge is made in the form of a single plate with a slot on one side. Therefore, the light bulb must be pulled out of it with little effort, because its contacts will cling to the socket.

Replacing warning lamps and backlight bulbs

We lay the VAZ 2103 dashboard on a smooth soft surface face down and see the backlight and indication lights (see the very first photo). I hope that before removing the dashboard, you found out which bulbs burned out and, using the recommendations above, purchased new ones of the right type. As I already indicated above, backlight lamps can be sold both with sockets, ready for installation, and without them.

We can easily remove the lamp together with the socket directly from the rear side of the instrument panel of the VAZ 2107 (in the photo is the PP of another VAZ model)

If you purchased lamps with sockets, then simply install a new one to replace the burnt one and fix it by turning it clockwise. If the light bulb was purchased without a socket, then you need to first remove the burnt one from the socket and install a new one in its place. The lamp is removed by lightly pressing it and turning it counterclockwise.

To remove the light bulb from the socket, you need to press it and turn it 90 degrees.

After this, we install the finished light bulb-socket set in its place. All that remains is to put the PP in place, not forgetting to connect 3 power connectors, 3 wires of the heater switch, the speedometer drive and the vacuum hose.

How to fix the dashboard backlight on a VAZ 2107?

One of the breakdowns that does not directly affect the operation of the car, but causes a lot of trouble for the driver - the backlight of the VAZ 2107 instrument panel does not work. During the day the problem is invisible, but at night the missing backlight significantly complicates driving your VAZ 2107. Because of this malfunction It becomes impossible to see the readings of the main instruments: tachometer, speedometer, econometer, fuel level indicators, charge level, coolant temperature.

The reason that the backlight of the VAZ 2107 dashboard does not light up is most likely the failure of incandescent lamps. Therefore, to eliminate it, you will need to replace the damaged light bulbs with new ones. The task is simple and requires a minimum of tools and skills. However, in order to access the bulbs, you will have to remove the entire dashboard. Armed with a flathead and Phillips screwdriver, you can get to work by first removing the positive terminal from the battery.

First, you need to remove the plastic handles from the heater valve and air damper control levers and unscrew the nut securing the daily counter reset handle so that they do not interfere with removing the VAZ 2107 dashboard.

Next, you need to use a Phillips screwdriver to unscrew the self-tapping screw hidden behind the plug next to the above-mentioned levers. The instrument panel is freed, it remains to perform a few simple manipulations to remove it completely and begin the repair:

Unscrew the speedometer cable nut;
Disconnect the hose from the econometer;
Disconnect the three electrical connectors.

After this, we remove the instrument panel of the VAZ 2107 and begin replacing the failed light bulbs. Everything here is completely simple, we take out the burnt out ones and install new ones in their place.

Thus, on the VAZ 2107, both the backlight and control lamps are replaced. Their location diagram is shown in the following figure.

Here the number 2 indicates the instrument panel backlight lamps. The remaining lamps are control lamps:

Fuel level;
Direction indicators;
Engine control systems;
Turning on the side lights;
Engine oil pressure;
Activation of the handbrake;
Turning on the high beam;
Battery charge.

It should be noted that many car enthusiasts, having reached the instrument panel of the VAZ 2107, do not bother with trivial repairs and perform backlight tuning. To do this, instead of conventional light bulbs, LEDs of the appropriate size are installed. Thanks to this modernization, lighting works more efficiently. You just need to choose the right resistance (resistor) connected in the circuit in series with the LEDs. In addition, you can stick stylish scales on the instruments instead of dull standard ones. Another option for implementing LED backlighting is to install lighting elements not in standard places, but along the perimeter of the panel. This method requires large material costs, but the result is more effective.

Reassembling the dashboard is performed in the reverse order:

The electrical connectors, the econometer hose, and the speedometer cable are connected in series;
Install the panel in its regular place;
Fix it with a self-tapping screw and put the plug in place.
Put the handles in place and secure the daily counter reset handle with a nut.

As a result, the instrument lighting works, the task can be considered completely completed.

What kind of lamps are needed?

Before disassembling your VAZ, it makes sense to drive it to the nearest auto store and stock up on new light bulbs. But which ones to buy? Judging by the first photo, the backlight and indication lamps have different sizes. The choice is simple: if the backlight bulbs have burned out (position 2 in the same photo), then you will need AMN 12-3-1 (T3W) bulbs. If they are indicator ones, then A 12-1.2 (Wl.2).

LED light bulbs

If you are tired of changing light bulbs in the power supply of your VAZ or are just a fan of modern tuning, then you can install LED light bulbs instead of incandescent ones, since the industry also produces those that have the same standard size, base, socket and operating voltage.

LED lights for the dashboard illumination (left) and indication for the VAZ 2107 car

Important! The battery charge indicator lamp cannot be changed to an LED one - the battery will not be charged properly.

Light bulbs - indicators

The electronic part includes seven light bulbs located in the center of the dashboard, in one column. To the left of them, the shield has dial indicators: tachometer, econometer and coolant temperature sensor, and to the right, symmetrically to the left side: speedometer, fuel level and battery charge sensor. Let's start with the light bulbs:

Direction indicators - located at the very top of the column, blink when the turn signal is turned on;
The malfunction sensor of the system responsible for engine operation is the second indicator from the top. Used only on VAZ 2107, with an injector engine. The carburetor engine shield includes this light, but it does not carry any symbols.

During normal operation of the system, this indicator lights up for a few seconds when the injector starts, and soon goes out. If there is a malfunction in the system, the light will flash, provided that the engine is running. Also, flashing means that a breakdown in the system allows you to get to the service station under your own power. I changed the bulbs in the foglights with the language of what kind of bulbs are in a Nissan, maybe MTF. If the light is constantly on, then the engine must be turned off immediately. Driving this vehicle is strictly prohibited;

The indicator showing the battery charge level is the third light from the top. When the battery is charged normally, it lights up when the key is in the “ignition on” position. Once the engine starts, the light should go out. If this does not happen, then your battery has a critical charge level. What kind of light bulbs are there in - cr-v.su. But, do not rush to go charge it, because if it is discharged during the operation of the car, it means that it did not receive a charge from the generator. The reason may be: a loose alternator belt, a malfunction of the mechanism, or a breakdown of the control lamp indicating the charge level. In any case, driving on such a battery is prohibited, since the charge may be lost at any moment and the car will not start;
The side lights light is the fourth from the top, lights up when the low/high beams are off, but when the side lights are on;
The high beam lamp is the fifth from the top, activated when the high beam lights on the car are turned on;
The low oil level sensor is the second light from the bottom. During normal operation, it lights up when the ignition is turned on, and goes out when the engine starts. If, after the engine has started, the light continues to light, this indicates one of two reasons: a malfunction of the engine lubrication system, or insufficient oil level. In the first case, the reasons may be: oil pump, highly liquid state of the oil, clogged cooling system. In the second case, the malfunction can be eliminated by simply adding oil to the cylinder block.

How to make illuminated arrows with your own hands

If you want to make the backlighting of the PP more interesting, then you can experiment a little. I offer one of the lighting options for the VAZ 2107, in my opinion, the most effective. To implement the idea you will need:

Conventional indicator LEDs of the desired glow color.
Resistors (according to the number of LEDs) with a nominal value of 550 Ohms.

First you need to disassemble the dashboard to get to the front side of the circuit board. We solder a resistor to the anodes of each LED and fix each pair along the inner perimeter of the instrument panel using a hot glue gun or sealant.

Using short pieces of wire, we connect all the cathodes of the LEDs and separately all the free terminals of the resistors. After this, we remove the standard backlight bulbs and solder wires to the current-carrying contacts of any of them - from the resistors to the “+” power supply, from the resistors to the “-”. The backlight connection diagram will look something like this:

Electrical diagram for connecting homemade illumination of pointer instruments for VAZ 2107

The more LEDs are used, the brighter and more uniform the illumination of the instrument scales will be.

Now you know how to replace the backlight and display bulbs in the dashboard of a VAZ 2107 car and, I hope, you can easily cope with this problem yourself.

We disassemble the buttons and replace the backlight in the VAZ buttons

The very first thing to do is remove the buttons from the machine. Then we disassemble them and take out the old backlight. To disassemble the button, pry up the top part and remove the cover from it. Next, you need to solder two LEDs into the button, one of which (red) is soldered into the pointer, and the second (white) into the illumination of the pictogram, as in the photo.

According to the author, it is worth noting that it is in the power window buttons that the backlight is easier to change than in all others.

In order to replace the lamps in the lighting fixtures of your car, it is not at all necessary to go to a service station and pay a highly qualified specialist. All operations can be done independently with minimal effort and money. Today we will talk about replacing light bulbs in the dashboard (DP) of a VAZ 2107 car.

Location of lamps on the instrument panel of VAZ 2107

The photo shows the reverse side of the vehicle's instrument panel. Light bulbs are marked with numbers. Four of them under No. 2 are backlight lamps, the others are control lamps.

They are placed on the board and are created for visual information to the driver. Any of them shows the operation of certain systems, components and assemblies of the car:

Alarm for low amount of gasoline in the tank.
Device lighting.
Monitoring the operation of direction indicators.
Signal about lack of battery charging.
Indicator of included side lights.
Low oil pressure alarm.
Indicator of the applied handbrake.
High beam indicator.
Alarm about malfunction of the forced injection system on engines.

Circuit breakers

First, check the fuses, they are located in the mounting block under the hood on the right side (pictured under No. 5).

Fuse F10 is responsible for the device panel.

If the fuse link has melted, it means there is a short circuit. It makes sense to examine the part of the electronic circuit for which this fuse is responsible. Perhaps it worked due to the burnout of one of the lamps or the influence of external causes on a section of the circuit. If the fuse is intact, you should investigate further.

Faulty incandescent lamps

If everything you did above did not produce any results, you need to remove the panel and check all the light bulbs.

Failure of incandescent lamps involves burnout of the tungsten filament. In another case, there may be a physical impact on the lighting device, after which it will not be able to work.

You can check it visually, alternately removing it from the sockets of the electrical board and inspecting the integrity of the tungsten filament. Or using a multimeter.

To eliminate all the reasons why lighting and signaling devices may not work, it is worth checking the integrity of the conductive paths marked on the electrical board.

Due to exposure to the environment, they oxidize and destroy. Easy to remove. It needs to be found, cleaned and soldered. It is also worth checking the terminals connecting the wires.

Incandescent lamps

AMN 12-3-1 lamps are installed to illuminate the device panel.

Lamps of brand A 12-1.2 are installed as signal lamps.

What to do if the instrument panel on a VAZ 2109 does not light up

When the instrument panel on a VAZ 2109 does not light up, this is one of the common malfunctions of this unit. To fix a problem, you first have to find the cause of its occurrence.

Types of panels

Instrument panels on the VAZ 2109 are of at least three types:

On versions with a low panel, failure of the entire panel is extremely rare. This is due to the fact that here the speedometer and econometer are equipped with mechanical drives. Therefore, it is unlikely that they will fail along with the electrical component.

Why doesn't it light up?

First, remove the cover of the mounting block and make sure that the fuse is intact. The fuse markings are located on the inner surface of the cover. You should look for fuse F16 or F5, depending on the year of manufacture of your VAZ 2109.
If the fuse is intact, be sure to check whether the contacts of the fuse you are looking for have not oxidized. It is not uncommon for shields to fail due to broken contact.
Check if there is power to the dashboard. To do this, you will need a warning light and the ignition on. Disconnect connector X4 in the mounting block and check for voltage at pin 3. The disadvantage of the VAZ 2109 design is that when it rains, the mounting block immediately becomes wet. This causes oxidation of the contacts in the pads, which causes the electrics to stop working. Sometimes not only the contact is oxidized, but also the board of the Nine mounting block.

If none of the above actions yielded results, you will have to be disappointed. After all, now you need to remove the dashboard and check the condition of the wiring, contacts, and negative connections. Here it is better to trust a professional electrician or set aside a whole day to troubleshoot problems yourself. There is no need to rush here.

Popular faults

If we talk about the dashboard of VAZ 2109 cars, then they are characterized by certain problems. We will tell you about them, and also tell you how to act correctly in a given situation.

The instrument panel of the VAZ 2109 is not so complicated that you cannot figure it out on your own. But in the absence of experience, it is better to entrust the repair to specialists, or to enlist the support of a partner who understands this matter.

VAZ-2107 instrument panel diagram

The instrument panel is an important part of every car, and the 2107 is no exception. For visual perception, it is better to look at what the VAZ 2107 “tidy” diagram looks like.

1 — automobile voltmeter;

2 - speed indicator or, more simply put, speedometer;

3—machine trip meter—odometer;

4 - tachometer. It shows the frequency at which the crankshaft rotates. The yellow zone on the scale indicates that the engine is running at high speeds; the red zone indicates unacceptable modes. 6000 rpm is the maximum permissible speed.

5 - coolant temperature indicator. The green zone is the normal coolant temperature. The red zone indicates engine overheating. The vehicle must not be operated at a coolant temperature exceeding 118 °C;

6—econometer. This indicator helps you select the most economical mode for engine operation from all modes (the instrument needle should be in the green zone of its scale).

7 - block (CL) of warning lamps of the VAZ 2107 car:

— turning on the turn indicators (when turning on a left or right turn, it lights up with a flashing green light);

— malfunction of the engine control mechanism (used on a car with an injection power unit. The lamp glows orange if the ignition is on. When the engine starts, it goes out). If there is a malfunction in the system, the lamp flashes or is constantly on. In such a situation, using the car is not prohibited, the system will simply switch to backup mode;

— battery charge lamp. When the ignition is turned on, the lamp on the instrument panel turns red and goes out when the engine starts. If the lamp continues to light, the battery is not charged. There may be several reasons: the generator drive belt is insufficiently tensioned, the control lamp or generator circuit is faulty. If you continue to use the car, this may lead to the battery being completely discharged and the engine stopping. A fire may also occur;

— side light indicator (lights up green if the side lights are on);

— indicator for turning on the high beam of the car’s lighting devices (the lamp lights up blue if you turn on the high beam of the headlights);

— insufficient oil pressure. When the ignition is turned on, the oil pressure lamp begins to glow red and immediately goes out when the engine starts. If the light remains on, there is low oil pressure. To avoid failure of the power unit, you need to turn it off and try to eliminate the cause of the malfunction;

— the parking brake is on (the lamp lights up bright red if the ignition is turned on and the parking brake lever is raised).

8—indicator of the path traveled per day;

9 — (CL) fuel reserve. The yellow light comes on if there is less than 6-4 liters of fuel left in the fuel tank;

10 — fuel level indicator;

Lada 2107 PHOENIX › Logbook › Replacing lamps in the dashboard

Perhaps one of the most noticeable tuning steps for the driver is dashboard tuning. There are a lot of recordings of this type on the drive, and it is quite possible that mine will be just another one... However, I will tell you about what I have not seen in other articles.

First you need to buy all the necessary components, in particular: Look at photo No. 3. On the left is what it was. On the right is what was installed.• LED lamps: 4 pcs. (bottom right) white light + 7 pcs. (top right) of which 3 pcs. red light, 2 pcs. green, 1 pc. blue, 1 pc. white.• Base (holder) for a small lamp. (top left)• 25 Volt electrolytic capacitor, 2000 - 4000 Microfarads

Next, you need to completely remove the dashboard and take it to a place convenient for work. In general, this is not difficult, but you will have to get dirty. You can search for how to do this on the internet, for example here: 2107club.ru.

After we have washed the panel from dirt, we proceed to modernization. For work you will need image No. 1. It shows the polarity for the LEDs using red and blue dots, which you need to know, otherwise the lamps will not work. You can check the polarity on the lamp itself “at random” using a 12-volt DC power supply or at least a 9-volt “crown”

(!ATTENTION: LEDs do not like polarity changes and may fail.). Personally, I used colored LEDs, however this is not necessary and you can use all white

We change everything except one - the low battery indicator, in image No. 9. This lamp cannot be replaced.

And now about the nuances. In several articles I came across the opinion that the green translucent caps in which the backlight lamps are located are not needed, supposedly because of them the light is dimmer. This may be so, but these caps are necessary for sealing so that dust does not get under the “glass” of the panel. I strongly do not recommend touching them. Moreover, the brightness with them is quite normal. True, they give an emerald tint of glow (seen in photo No. 2). Personally, in my case there were problems. The turn indicator lights up for a while after turning off the turn, after which it flickers a little. What this is connected with is not clear. I solved this problem in the wrong way: I soldered and glued the old lamp onto the board, parallel to the LED. I haven’t been able to solve the following glitch yet: the “dimensions/low beam” indicator glows faintly when the switch is in the off position. I tried to connect in parallel a fragment of the LED strip glued to the right side, but the problem remained. But now, when I turn on the headlights/low beam, the space behind the ventilation control levers lights up.

What is the capacitor for? And in order to eliminate the twitching of the fuel level needle. Connection diagram in image No. 1. If you need it, of course. It is worth noting that after this upgrade, when the ignition is turned on, the needle will rise smoothly until the capacitor is fully charged, and when turned off, it will beat to maximum. The severity of these effects depends on the capacity. The larger the capacitance, the better the smoothing, but the stronger the side effect. I do not recommend using a capacity less than 2000 and above 10000 uF.

Also, I soldered a 25 V 10000 uF capacitor in parallel with the dashboard backlight lamps. True, I already doubt its usefulness...

In image No. 2 you can see the areas outlined with a green marker, this is for those whose panel creaks. I applied two layers of adhesive tape to the plastic pins. I taped other contact points with black electrical tape. For example, along the edges of the “glass”, before returning the panel to its black body. And also the body itself, as well as the rim. So that the points of contact with the dashboard are “isolated”. No photos, sorry.

In conclusion, I will say that all the modifications are worth it. The panel looks livelier, newer, more modern.

Location of lamps on the instrument panel of VAZ 2107

The photograph shows the reverse side of the car's instrument panel. Light bulbs are marked with numbers. Four of them under No. 2 are backlight lamps, the rest are control lamps.

They are located on the board and are intended for visual information to the driver. Each of them indicates the operation of certain systems, components and assemblies of the car:

Alarm for low amount of gasoline in the tank.
Instrument lighting.
Monitoring the operation of direction indicators.
Signal about lack of battery charging.
Indicator of included side lights.
Low oil pressure alarm.
Indicator of the applied handbrake.
High beam indicator.
Alarm about malfunction of the forced injection system on engines.
