What should I do if the lights are always foggy in rainy days?

Fogging of car lamps in rainy days is mostly caused by air leakage or water ingress. If it is serious, it is recommended to go to the 4s shop for car light maintenance.

Fogging of headlights will reduce the lighting effect, and the headlights will be scrapped over time, which will greatly reduce the service life of the headlights. It is best to deal with similar problems in time.
