5 easy ways to keep headlight bulbs from burning out

Many cars have halogen headlights, and they often burn out. And for some models, this has become a real problem. The AvtoVzglyad portal will tell you why this happens and what to do so that the light bulbs do not quickly fail.

The layout of the engine compartment of most modern cars is such that not everyone can quickly change a burned-out “halogen bulb” in the headlight. Often, to get to the lamp, you need to remove the battery from the car, and sometimes completely dismantle the front bumper. In general, this is not only a hassle, but also a rather costly business. How to be in order to increase the service life of the lamps and maximize their life?

Reduce voltage (software)

This method is suitable for new cars with a lot of electronics. To extend the life of the optics, you need to reduce the voltage to the lamps using special voltage regulators. And if the driver is dissatisfied, they say, the headlights have become worse to illuminate the road, the voltage can be easily raised back. For such a task, you need a special scanner for auto diagnostics. A simple reprogramming operation will take no more than five minutes. So the headlights of your car will shine a little worse, but they will last longer.

Checking the generator

Incorrect voltage of the on-board network can also lead to the fact that the “halogens” will not withstand and burn out. For example, if the voltage regulator relay on the generator fails, then up to 16 V can go to the network. And lamp manufacturers usually rely on their products for a voltage of 13,5 V. Lamps cannot cope with such a load.

We repair wiring

This tip applies to older cars. It's no secret that old wiring gives large voltage losses, and over time, its contacts also oxidize. In addition, the lamp clips in the headlight can be worn out, and because of this, the “halogen” constantly vibrates.

Therefore, in an old car, you must first check the correct installation of the lamps and the condition of the headlights, then clean the oxides on the contacts, and in advanced cases, change the wiring.

Only without hands!

Halogen lamps burn out quickly if handled by the glass with bare hands. Therefore, if you do not want to climb under the hood once again, change the lamps with gloves or wipe the windows so that they do not leave greasy finger stains.

We remove moisture

Often, even in new cars, block headlights sweat, and moisture is a thunderstorm of “halogens”. Fogging can be caused by moisture penetrating through ill-fitting rubber seals that are located between the headlight housing and glass, as well as through headlight vents.

If a new car starts to fail due to such fog, then, as a rule, dealers change the headlights under warranty. In the event that the warranty is over, you can open the headlight plugs in a dry and warm garage so that the air in the headlight mixes with the surroundings faster and fogging disappears.

There are also more radical ways. Let's say some craftsmen change the headlight ventilation scheme. This is done, for example, by the owners of Ford Focus and KIA Ceed, which is full of information on specialized forums on the Web.
