The dangers of car headlight fog
The fog in the headlights will seriously affect the normal light transmittance, and even cause the direction of the headlight beam to shift, causing astigmatism. The scattered light is not focused and has no penetrating power. After some people change to brighter light bulbs, the light is very strong from a distance, but they can't see the road clearly. This is caused by astigmatism.
Causes of fog and water accumulation in car headlights
In fact, all lights have a ventilation rubber tube on the back cover. The function of the rubber tube is to remove the heat generated after the headlight is turned on and maintain the normal operating temperature of the headlight. It is precisely because of the existence of this rubber tube that The moisture in the humid air will adhere to the lampshade and form water mist.
Moreover, when the temperature difference is large, a large amount of accumulated water vapor will flow down the lampshade to form some accumulated water. However, if there is accumulated water in the headlight, it does not necessarily mean that there is a problem with the sealing of the headlight. This is also the case when the temperature difference is large. normal.
How to deal with fog and water accumulation in car headlights
If after encountering water, it is found that the amount of water in the headlight obviously exceeds the standard, forming a large amount of water, this situation can basically be determined to be a problem with the headlight seal. In this case, you need to remove the headlight assembly and carefully check whether the light, back cover, and ventilation rubber tube are damaged.
After confirming that there is no damage, peel off the assembly, dry it separately, and then reseal it.
Notes to drivers
The best way to solve the problem of foggy headlights is to turn on the headlights. You cannot directly use a dryer to bake the headlight masks, because most of the lampshades on the market are made of plastic, and the baking temperature is too high, which will cause the headlights to age. Turn yellow and even crack when exposed to cold.
