How to Deal with Water in Car Headlights?

[McEmilia]

Car headlights water ingress treatment methods are: 1. For slight water ingress in the headlights, turning on the headlights will generate a large amount of heat (halogen lamps produce heat), which directly evaporates the water, and the water vapor will be expelled from the light through the vent pipe along with the hot air; 2. In case of severe water ingress, do not turn on the lights. Instead, remove the headlight housing and open the lens to air dry. At the same time, it is necessary to inspect the surface of the headlight for any damage or potential leakage points. If any abnormalities are found, replace them immediately. After water enters the headlights, it is important to note that never use a hair dryer on the headlight housing, as this can damage the headlight. Headlight housings are made of plastic material and can easily melt under heat, and such damage is irreparable.
