However, there isn't just *one* headlight fuse. There are usually separate fuses for the high beams and the low beams, and possibly even a relay involved. The fuse box cover itself should have a diagram showing which fuse controls what. Look for fuses labeled something like:
* Headlamp (Low Beam)
* Headlamp (High Beam)
* Headlight Relay (This might be a relay slot, not a fuse)
Without the diagram from your specific vehicle's fuse box cover, it's impossible to give you the exact fuse number. Refer to the diagram on the inside of the fuse box cover. It's crucial to use this diagram because the fuse layout can vary slightly between models.
