1978 F150 Headlights
Both headlights went out as I pulled the **** turning them on. All other lights work fine, just no headlights high or low.
Trying to locate fuze / relay
Any Ideas?

Trace wiring back from headlights, find common point where they meet up and look for a broken wire from there.

Pull the headlamp switch **** all the way out, step on the floor mounted dimmer switch, then see what happens.
The switch corrodes, so if the low beams are on and you step on the switch, the headlights will go out...and vice versa.
