As a rule, the cause of low beam malfunction on a VAZ 2110 is burnt out light bulbs. However, sometimes the lack of lighting is due to the failure of other components. Below we will look at how to replace lamps, as well as the most common reasons why the low beam does not light up and how to eliminate them.
Low beam of a VAZ 2110 car
High or low beam does not turn on
The inability to turn on two high beam headlights requires a mandatory check of relay K5. It is located in the mounting block located in the cabin (to the left of the steering wheel).
How to find out if this relay is working. Pull it out and place a jumper between the 87 and 30 connectors of the block. After this, try to turn on the light. The activation of the headlights indicates a breakdown of the above-mentioned unit. It cannot be repaired in principle, so it will have to be replaced.
The reason for the failure of both low beam lamps is diagnosed in the same way, only you will have to close contacts 87 and 30 on the K4 relay block - it is the relay that is responsible for this electrical circuit.

General information
Modern models of the Volzhsky Automobile Plant are equipped with many devices, including many lighting ones. All of them are connected to a single electrical circuit of the car, but they perform different functions.
So external lights and signals serve for:
- road lighting at night;
- determining dimensions;
- demonstrating to other road users the car enthusiast’s intentions.
In addition, there are also light bulbs in:
- salon;
- trunk;
- engine compartment.
External devices include:
- side and signal lights;
- block headlights;
- rear lights;
- fog lights;
- number plate illumination.
The headlights have a special adjustment device - a corrector. With its help, the driver, without leaving the cabin, can direct the light up or down depending on the need.
The filament in the light bulb has burned out
To replace a light bulb, it is not at all necessary to contact the services of an auto electrician. All you need to do is follow these steps:
- open the car hood;
- remove the protective cover on both sides of the headlight;
- disable contact group;
- remove the spring clips;
- remove the burnt out light bulb;
- insert new one;
- Carry out all preparatory steps in reverse order.
At the same time, we should not forget to follow some rules:
- It is recommended to wipe the surface of the flask with alcohol before installation, otherwise it may immediately burn due to the presence of greasy or dirty stains;
- Do not touch the flask with unprotected hands, as this may lead to contamination of its surface. This is best done with cotton gloves, but you can also use a napkin or rag.
The high beam on the VAZ 2111 does not light up
In addition, their service life is approximately the same, so if one of them burns out, the second one will soon fail.

Where does the low beam on the VAZ 2110 turn on? Auto repair So, there is a known case when the owner of a Niva turned off the low beam after he dismantled the headlight cleaners, which had long ceased to function. Ask, I'm in touch!
Adjustment
Once a year, the low beam on the VAZ 2110 should be adjusted. This procedure is necessary in order to increase the lighting efficiency and also to prevent dazzling oncoming drivers.
Below we will take a closer look at how to adjust the low beam headlights:
- You need to find a flat area with a wall that will serve as a screen.
- The car should be placed at a distance of five meters from the screen. A passenger must sit in front. You can also put a load weighing 75 kilograms in the car.
- On the screen you need to draw a horizontal line at 600 mm, as well as a second line 75 mm below the first.
- Then you need to draw three vertical lines - the two outer lines should correspond to the centers of the headlights, and the middle one should be located in the middle between them.
- The headlight hydraulic adjustment handle should be moved to the position corresponding to the minimum load.
- One of the headlights must be covered with cardboard or a sheet of plywood.
Adjustment screws
- Then the light beam is adjusted according to the diagram. Adjustment is carried out with screws with plastic heads, which are located on the back side of the headlights. They rotate the optical element around the horizontal and vertical axis.
- Next, you need to adjust the second headlight in the same way.
Here, in fact, is all the information on how to adjust the low beam headlights.
Fuse burned out
For this reason, one low beam headlight often does not light up. To eliminate it you need to do the following:
- open the block that contains all the fuses of the automobile electrical circuits;
- Using the diagram, the fuse that is needed is determined. As a rule, if it has burned out, it is immediately visible;
- replace the faulty element with a working one.
By the way, if blown fuses become a frequent occurrence, then you should look for a breakdown in the wiring. To determine it, you need to ring all the elements of the electrical circuit, or seek help from specialists. Moreover, this must be done without fail, since the presence of a short circuit can cause a fire.
Diagnostics
If problems arise with the vehicle's lighting equipment, the cause of the problem should be identified as quickly as possible and eliminated. The search should begin with the simplest and at the same time the most common causes. So, if one headlight on your VAZ 2114 does not light up, then most likely the reason is that the bulb of this headlight has burned out.
The simultaneous burnout of two light bulbs in both headlights also happens, but is extremely rare. As a rule, this occurs during sudden changes in voltage in the network and is accompanied by serious damage to other electronic equipment. Checking the serviceability of the light bulbs is very simple - you just need to replace them with new ones.
When going on a trip, you should definitely have a set of spare lamps with you.
If, after replacement, the new light bulbs also refuse to work, then you should move on to the next stage - checking the condition of the sockets themselves. They very often become covered with a layer of oxides and stop transmitting current to the lamp. In order to fix this, you should carefully clean the nests with fine sandpaper or wipe them with a hard cloth soaked in kerosene or VD-40. If this also does not help, then move on to checking the circuit.
In order to check the integrity of the electrical circuit, you should “ring” the wires leading to the headlights from the fuse box with a tester. If there is a signal, then the wires are working; if not, then there is a break and the wires should be replaced with new ones.
The next step of the test (although it can be done first) will be to check the fuses located in the common block. In this case, two 7.5 ampere fuses, labeled F12 and F13, are responsible for protecting the headlights. The first of them is in the right headlight circuit, and the second is in the left one.
The failure of one of them will lead to a breakdown of the light on only one side (this feature, along with the burnout of one light bulb, may be the reason why only one headlight is on). Solving this problem is extremely simple - you just need to replace the fuses with others designed for the same current strength.
After all the methods described above have been tried, and you still have not been able to figure out why the low beam is not on and the high beam is on on the VAZ 2114, then you should check the last possible reason - the headlight switch button. First, you should check how the wires are attached to it - they have not come loose or oxidized. If everything seems to be working fine, then you need to check the button itself. The easiest way to do this is to replace it with a new one (fortunately, it costs a little more than a hundred rubles).
Finishing the conversation about possible malfunctions, it is worth mentioning an extremely rare but possible reason - a breakdown of the K9 relay (it is located in the common block). If a complete check of all electronic elements and replacement of the power button do not produce results, then this relay should also be replaced. Such a replacement should help correct the situation and return both headlights to operation.
Other reasons why one low beam headlight does not light up
Sometimes the abnormal operation of headlights lies in very unusual reasons. Thus, there is a known case when the owner of a Niva turned off the low beam after he dismantled the headlight cleaners, which had long ceased to function. As a result, for a long time he could not understand why the low beam on both headlights turned off.
What kind of lighting do you prefer?
Built-in Chandelier
Only through experimentation did he manage to discover that for the headlights to work normally, the presence of any motor, be it left or right, is necessary. Ultimately, it was necessary to create an imitation of the presence of these elements by closing the contacts going to them.
In cases where all of the above measures were taken, but it was not possible to achieve normal operation of the low beam lamp, you should contact specialists at a service station. Otherwise, further searching for the reason why one low beam headlight is not on may take a lot of time without achieving the desired result.

Wiring
Let's go further along the chain. You need to find out if there is voltage at the headlight unit. To do this, you need to measure the voltage at the lamp plug. If there is voltage, but the lamp does not light, then:
- the lamp burned out,
- The chip melted or for other reasons lost its functionality.
If there is no voltage, then you need to look for where the break is!
Having problems with the wires
To eliminate this malfunction, you will have to check all the blocks through which the relay and fuse box are connected. It is possible that there is a poor-quality connection, as well as oxidation of the contacts, which leads to an increase in the current flowing in these places and their heating. To eliminate such malfunctions, it is enough to tighten all the pad fastenings, having first thoroughly cleaned all contacts using sandpaper or a needle file.
It would also be useful to check the button with which the headlights are turned on, since its contacts are also subject to oxidation and they may also have a poor-quality connection. Practical experience suggests that it is from this button that you should start troubleshooting, and only after making sure that it is fully operational, continue searching for the reason why the low beam does not work.
Fuse
- The control relay has failed. Such a malfunction requires the involvement of service station specialists. It is unlikely that you will be able to change the relay yourself without the necessary knowledge.
- The fuse has blown. If problems are detected with the head light, it is worth starting the diagnosis with the serviceability of the fuse insert. If it is damaged, replace the fuse. To avoid problems, it is worth having several sealed parts of different denominations in the glove compartment or trunk.
- The light bulb has burned out. In modern cars, various lamps are installed, the cost and quality of which differ. There are quite expensive lamps, and not every car owner will decide to buy them. Regardless of the price, it's worth keeping at least one spare bulb in your car. Such foresight can save you if the high beams are not on, and you urgently need to go somewhere at night.
PRICES OF COMPONENTS
There is also a separate section for prices for all the parts that may be needed when repairing this part of the car, because if the side lights on a VAZ 2114 or the fuses have blown, they will still have to be replaced with new ones. In any case, all the components are quite cheap, all we might need:
- Marker lamp;
- Fuse;
- Power button;
- A whole fuse block.
Today, an ordinary white light bulb costs up to 30 rubles; of course, the price depends on the individual pricing policy of a particular seller. Individual fuses can be selected for up to 50 rubles, unless, of course, you want to install a higher quality option. Button, if you look for exactly the same one as the original one, you will have to pay up to 300 rubles. In some situations, more serious problems may arise and you will have to change the entire unit, this is quite an expensive proposition, together with all the wires it will cost up to 1000 rubles.
Based on this, we can say that you need to carefully monitor your car and try to avoid any serious malfunctions; if something breaks, fix it right away, don’t start it.

Fuses VAZ 2110 - 2112
Now let's see which fuses are responsible for what in the same mounting block. I will also give the main reasons for troubleshooting.
Purpose of block fuses
F1 (5 A) - license plate lighting lamps, dashboard lighting, side lights on the panel, trunk lamp, left side lights.
If any of the listed lamps do not work, check this fuse, as well as the lamps themselves and their contacts. If everything is in order, check the headlights switch.
If both low beam headlights do not work, also check relay K4 and the lamps themselves. It could also be the light switch and its contacts.
If both high beam headlights do not work, check the K5 relay, the lamps themselves and the high beam switch knob.
F4 (10 A) - front fog lamp on the right side.
If both fog lights do not work, check relay 9 and the headlight bulbs themselves, as well as the switch and its contacts.
F5 (30 A) - window lift motors.
If the power windows do not work, check this fuse and relay 5. In winter, check if the windows are frozen, warm them up and clear them of ice if necessary. It could also be the window lift motor, its mechanism and gears; in order to get to it, you need to remove the trim of the desired door.
F6 (15 A) - portable lamp fuse.
There may also be problems with the cigarette lighter. To check, unplug the cigarette lighter from the connector. If this fuse stops burning, then the problem is in the cigarette lighter.
F7 (20 A) - engine cooling fan, sound signal.
If the cooling fan does not turn on and the engine overheats, check this fuse. Also check the operation of the fan motor by connecting it directly to the battery. It could also be the coolant temperature sensor or thermostat.
F8 (20 A) - heated rear window (element).
If the heating does not work and the rear window fogs up, check this fuse, fuse F9 and relay K7. Also check the contacts on the terminals of the heating elements, check the wiring, sometimes the wire frays. It could also be the heating switch and its contacts.
F9 (20 A) - recirculation valve, windshield wipers and washer, headlight washer, rear window heating relay coil.
If the heating does not work, similar to the previous one. If the windshield wipers or washer do not work, also check relay K2, the fluid level in the washer reservoir, the washer pump, and the wiper motor. Another issue may be their switching handle, its wiring and contacts. The wires may be squashed or frayed and shorted to the housing.
Replacing lamps

How do lights work on a car?
Malfunctions that arise may be in the nature of a complete failure of the headlights or their periodic inoperability; there may be cases when your light will burn dimmer than usual and intermittently.
High beam is usually adjusted for night driving on the highway, in contrast to the fact that low beam is often used during the day, in combination with fog lights. The easiest way to troubleshoot a complete failure of the VAZ 2110 light. In this case, there is a specific breakdown or malfunction that you can simply methodically identify and eliminate. In the case of periodic failures, and at the time of elimination, when everything is working, this malfunction is much more difficult to determine, since it can hide anywhere. Before searching for the reason for the failure of the low beam or high beam headlights, you should understand the mechanism of operation and the principle of operation, which is as follows:
Power from the battery is supplied to the ignition switch - then power goes to the side light switch - from which it goes to the light switch located on the steering column - then control goes from it to the corresponding relay in the fuse box, the steering switch turns on a certain relay, supplying voltage to his contacts.
Thus, if the lighting fails, you need to understand and find out in which part of the circuit the circuit break or voltage loss occurred. Or determine that the malfunction lies in the failure of the lighting lamps. On this car, the low and high beam are divided into two lamps in each headlight.
Let's consider the case when the right high beam does not work. Do not forget that the light is turned on by a relay, and in the event of a failure of the low or high beam of one headlight and at the same time the functionality of the other, this means that the light switching circuit before the relay is functioning normally and the cause should be looked for after the relay, starting with the fuses. Almost all circuits are protected by fuses, even installed additional accessories - navigator, video recorder, radar detector, receive power from the cigarette lighter, which is protected by a fuse
Fuse F13 is responsible for the far right fuse; we take it out and check for functionality; if by visual inspection it is not clear whether it works or not, replace it with a known-good fuse of the same power. When replacing it, two options are possible: the light will not light up or the fuse will blow. In case of short circuit. We need to look for its cause. Next, open the headlight and replace the high beam bulb. All this can be made a little easier if you have a test light at your disposal, which you can use to check whether voltage is supplied to the headlight itself, since removing the light bulb requires a little skill.
If you determine that when you turn on the high beam, the voltage approaches the headlight, then you can safely remove its pot from the back of the headlight and replace the bulb. There is one more malfunction, this is a break and loss of “mass” on the paw, take this point into account and do not rush to immediately spend money buying a new light bulb. Perhaps this wire is simply disconnected and when power comes to the lamp, there is no ground power.
