How to Avoid Frequent Burning Out of Headlight Bulbs?

The bulb in the car's headlight will burn out from time to time. What is the reason for this? I believe many riders will have the same doubts. The light bulb of a car is like the "eye" of a car. On the one hand, it ensures the safety of driving at night. On the other hand, it can bring you and your family a comfortable driving experience. Here are the main reasons why car headlights are often burned.

Causes and Solutions of Frequent Burnout of Automobile Headlamp Bulbs

The generator voltage is too high

The bulb often burns out, mainly because the generator voltage is too high. When the generator voltage is too high, the current passing through the filament will greatly increase, the filament temperature will be too high, and it is easy to burn off. The voltage regulator is misadjusted or improperly adjusted, so reasonable use of it can limit the high voltage at the generator terminal caused by too high voltage. During use, as long as the voltage regulator is properly adjusted, such problems can be prevented.

There is fog in the headlights

For the overall structure of the headlamp, whether it is a common halogen headlamp, xenon headlamp, or a headlamp with LED, there is a ventilation rubber tube at the rear cover. At the moment when the headlight is lit, even when the headlight is used, a lot of heat will be generated. The function of the vent pipe is to discharge the heat from the headlamp as much as possible to maintain the normal working temperature of the headlamp and ensure the use of the headlamp. At this time, the water vapor in the air will enter the headlight and attach to the lampshade. With the accumulation of water vapor, water droplets flow down the lampshade. This situation is mostly caused by the large temperature difference. This phenomenon is most likely to occur in the winter and rainy seasons.

In this case, don't worry too much. After the lamp is turned on for some time, the fog will be released through the ventilation pipe, which will hardly damage the headlamp and the circuit. In this case, the driver must not do anything rash, such as baking the headlamp, which is easy to damage the headlamp, because the appearance of the headlamp is plastic, and the extra heat is easy to bake the lamp cover, and most of the damage is irreparable.

Human causes

In addition to weather changes, human factors will make the lights become "tearful eyes", such as vehicles wading and washing. In a wading vehicle, the engine and exhaust system are relatively hot. Rainwater will form a large amount of water vapor on them, and some of the water vapor will enter the headlights along the vent pipe.
