Usually, headlights use a resetting circuit breaker for headlights and not a fuse.
Look at the wires on your headlight switch. I had a 96 Vectra Grand Tour and one of the wires burnt in two. I spliced on a new wire. I also removed some of the bulbs in the lower front running lights to reduce current draw through the light switch.
I had installed separate tail light bulbs on my towed and after fixing the wire I replaced the bulbs in those tail lights with LED's to further reduce current draw through the light switch.
Later I had the headlight switch replaced and the spliced in wire was beginning to show charring of the insulation. I felt Winnebago just had too much current flowing through the exterior lighting system and should have at a minimum installed relays for the towed vehicle lighting.
