A car is a complex technical device with a plethora of different systems, sensors, components and assemblies. At the same time, the wrong operation of some can adversely affect the functioning of others. But what happens to low beams that don’t come on while high beams are working properly? The AvtoVzglyad portal revealed the reasons for such turmoil.

When it gets dark, during normal operation of the car’s lighting system, drivers turn on the low beams with the steering column lever. And if necessary, they also switch to a distant one. If headlights loomed in the oncoming lane, the process of switching from far to near occurs in reverse. However, it happens that when switching from far to near, the latter refuses to switch on. And this can become a serious problem at night. Therefore, if you notice a malfunction, you should immediately eliminate it. But where to start, and is there a relationship between high and low beam?

Let’s say the low beam in only one headlight refuses to work. As a rule, this is a problem in the lamp – it can simply burn out. By replacing it with a new one, the driver can easily fix the problem. When replacing it is of course worth inspecting the contact group for oxidation, as you have already climbed into it – this can also cause the lamp to go out. If traces of oxidation are visible on the contacts, they must be cleaned and lubricated with a special compound.

The reason why one low beam bulb can go out could be the fuse box or the fuse itself. If the lamp comes on when you move the block itself, then the contact is coming loose somewhere – you need to remove it. If the fuse is blown, replace the fuse.

But what to do if the low beam bulbs do not light up on both headlights?

One of the reasons could be the steering column switch itself. It could be that the wires are frayed somewhere or there are contact issues that could melt. If this happens, most likely the steering column switch needs to be replaced.

Many motorists often use low beam as CSR. Light bulbs in it spend their resource many times faster. Therefore, they may very well burn out one after the other.

During the summer season, many car owners often go to the country road – some to the rest area, some to the countryside, some just take a shortcut. As a result, the filaments in the lamps experience a heavy load from shaking and can also fail at the same time.

As you can see, there are many reasons why the closest one might not work when the far one works. However, there is no direct dependence on the operation of the dipped-beam headlamps from the main beam and vice versa. This means that you should not look for a black cat in a black room, especially if it is not there.
