Doc here,

RARELY do automotive manufactures use a "Headlight Fuse" at all..

The preferred method is a Thermal Reset INSIDE the Lamp switch..it senses over current by heat, trips until cool (unless catastrophic short) then resets.

SOME headlamp systems That use RELAYS , will employ a H/L fuse..this is actually the fuse for the relay coil..the actual power comes from the battery, Via a fuse link, to the N.O. set of contacts on the relay...Then the C.W. Contact when energized carries power to the lamps..

Don't forget to check the front end grounds..without those , the lamps wont work either..clamp a jump start cable to the battery , then to ground at the radiator support near the lamps to check..


Doc
