How to Deal with Water Inside Car Headlights?
1 Answers
If there is slight water ingress inside the headlight, turning on the headlight will generate a significant amount of heat, which will directly evaporate the moisture. The water vapor will then be expelled from the headlight along with the hot air through the vent tube. In cases of severe water ingress, never turn on the headlights. Instead, remove the headlight housing and open the lens cover to let it dry.
