If original, the fuse is in the headlight switch. A short or high amperage drawwould cause the lights to go on then off repeatedly. The switch has a bi-metalic strip that when heated up bends and opens a contact. Once cooled, which only takes a second or so, straightens back out and closes the contact completing the circuit. Thus the blinking lights.
