Is it normal for headlights to be foggy?

It is normal for the headlights of Pacific Auto Network to be foggy, because there is an exhaust pipe on the back cover of the headlights, which is mainly used for heat dissipation. The heat generated during lighting is discharged from the snorkel, but sometimes moisture will enter the snorkel, causing fogging of headlights.

Moisture in the air will enter the headlights through the snorkel and attach to the lampshade. With the accumulation of water vapor, water droplets will flow down the lampshade. This situation is mostly caused by large temperature difference, especially in winter and rainy season. After the headlights are turned on for a period of time, the fog will be discharged through the snorkel with hot air, which will basically not damage the headlights and electrical circuits.

In this case, drivers and friends should never act rashly and never bake headlights, which will easily damage them. Because the headlights are made of plastic, excess heat can easily melt the lampshade, and most of this damage is irreparable. In addition to weather changes, human factors can also make headlights change? Tears? , such as vehicle wading, car washing, etc. When a vehicle wades, because the engine and exhaust system are relatively large heat sources, a large amount of water vapor will be formed when rain falls on them, and some water vapor will enter the headlights along the snorkel.
