How to deal with water ingress from car headlights?
LED car headlights are different from the fogging of the headlights. We will find that the water vapor in the headlights is not water mist, but large water droplets. At the same time, we will also find that the water droplets in the headlights will not evaporate for a long time. Water will accumulate in the lamp cavity in serious cases. At this time, we should deal with the problem of water ingress in the headlights of the car. There are also many reasons for headlights flooding.
1. The ventilation holes of the LED car headlights are blocked.
When the vent holes of our LED car headlights are blocked, the air cannot circulate normally, and the speed of natural water evaporation will slow down, and the blocking of the vent holes is not conducive to the release of the pressure generated by the high temperature in the lamp cavity, and the long time will accelerate the aging of the lampshade. Caused our lampshade to burst.
2. The headlights are not tightly sealed.
Some vehicles may have imperfections of imperfect sealing of LED car headlights when they leave the factory, so excessive water will flow into the lampshade along the gaps when it rains and when the car is washed. However, there are very few cases where the factory headlights are not tightly sealed. More often, the secondary sealing of the headlights is not done well when we modify the lens and bulb of the vehicle and replace the headlights of the vehicle. Therefore, when we modify and replace the headlights, we must pay special attention to the sealing of the headlights.
3. The lampshade of the LED car headlight is damaged.
Vehicles travel very fast on the road. Sometimes splashing stones or foreign objects hit the headlights. Sometimes we just look at the surface of the headlights and there is no problem, but if there are small cracks in the lampshade, the same is true. It will cause the headlights to be tightly sealed and the headlights to enter the water. Therefore, our vehicles must be carefully checked after being hit by foreign objects to ensure that they are safe.
4. The design problem of LED car headlight itself.
We have seen that the headlights of many models are particularly fogging of fog. This is actually not a sealing problem of the headlight itself but a design problem of the headlight. For example, the lampshade is too small, the vent position is wrong, and the material of the lampshade And so on will become an incentive for headlights to fog. But this is a small probability event after all, and you don't need to worry too much.
For the fog of the headlights, Dahuyou's advice to everyone is to go with the flow, but if the headlights are flooded, you must not let it go. Because the water in the headlights will affect the line of sight of the lights and affect driving safety; in the worst case, it will accelerate the aging of the headlights and even cause the headlights to short-circuit. Avoid doctors, find out the cause of the problem in time, and ensure vehicle safety and driving safety.
