What to Do When There is Fog Inside Car Headlights?

[ORowan]

How to deal with fog inside car headlights is to turn on the headlights. Generally, after the headlights are turned on for a period of time, the fog will dissipate along with the heat through the vent pipe, and it will not cause damage to the headlights or the circuit. If the owner has a high-pressure air gun, they can also use it to blow air on areas in the engine compartment that are prone to moisture accumulation, speeding up air circulation to remove moisture. The following is an introduction to headlight fogging: 1. Since headlights need to dissipate heat, the heat generated when they are turned on needs to be released. There is a dedicated vent near the headlight for heat dissipation. When the headlights are turned off, they are still hot, and as they gradually cool, some moisture from the air may enter, thus forming fog. 2. Turning on the headlights for about ten minutes can usually remove the fog, which utilizes the heat from the headlights and is a normal phenomenon. However, if the fog cannot be removed after fifteen minutes or half an hour, it indicates that the headlight has water ingress and needs to be replaced.
