Is it normal for car lights to be foggy?
Fog is a normal phenomenon in car headlights. The key is that when the temperature of the headlight drops, the cold air from outside enters the inside of the headlight. When the hot air inside the headlight hits the cold lampshade, there will be a layer of fog. However, when the temperature of the hood and the temperature inside the lamp reach equilibrium, no fog will be produced and the fog will slowly dissipate.
This situation often occurs in winter or rainy days when the temperature is low. In such weather, the temperature difference between the inside and outside of the headlight is quite large. With this situation, friends don’t have to worry, because it will not have anything to do with the car. As long as you turn on the headlights for a while, the fog will dissipate.
For those who don’t understand, you should bake the headlights well in this situation, but it can easily cause problems with the headlights. Because hoods are basically made of plastic, if the baking temperature is high, the hood will be baked and not worth the candle.
In addition to the above situations, when water enters the car, it will also cause the headlights to fog up, which cannot be treated as a common phenomenon. We should open the lamp cover to dry, and then check whether there is leakage or damage on the surface of the headlight. If not, most of us basically replace the seal and breather tube on the back of the headlight. If the situation is serious, we should send it to a repair shop and let the repairman check what is wrong. Also, when washing your car, friends must be careful not to let water enter the car lights.
In continuous rainy days or humid weather, we need to do a good job in testing the headlights. In rainy weather, cars often have water wading conditions, and they should be tested immediately after wading. It is very important to repair any problems with various parts of the car immediately, otherwise it may cause major problems over time.
