Does each headlight have a fuse?

Depending on how your headlight circuit is set up, there may be one fuse or multiple fuses for the headlights. If you find a blown fuse, then replacing it may fix the problem. When replacing a blown headlight fuse, it’s important to use a new one with the same amperage rating.

What fuse should I use for headlights?
