What would cause the headlights and dashlights on a 1994 Ford Ranger XL to randomly go off for for 5-10 seconds then back on?

Answer 1

FIRST OFF CHECK YOUR WIRES TO THE HEAD LIGHTS AND TRACE THEM BACK TO THE CAB, YOU MAY HAVE TO OPEN UP THE TAPE AND PROTECTIVE COVERING ON THE WIRES. REASON FOR DOING THIS YOU HAVE AN EXPOSED WIRE IN TURN IS HEATING UP AND OVERHEATING. I HAD THE SAME PROBLEM WITH MY 91 RANGER XLT, FIND THE WIRE OR WIRES, FIND OUT WHAT GAUGE WIRE THEY ARE, CLIP THE EXPOSED AREA AT EACH END AND REPLACE WITH NEW WIRE! ALSO IF YOU HAVE FOG LAMPS THAT ARE AFTER MARKET THAT TURN ON WITH YOUR HEADLIGHTS YOU MAY BE OVERLOADING YOUR CIRCUT, RE-WIRE YOU LAMPS TO A SWITCH WITH AN INLINE FUSE, ALSO HAD THIS PROBLEM, FOUND OUT THE HARD WAY GOING DOWN THE INTERSTATE MIDDLE OF THE NIGHT, GETS A LITTLE FREAKY WHEN YOU HAVE NO LIGHTS PITCH BLACK. GOOD LUCK HOPE THIS HELPS YOU OUT! some times the headlight switch will do this
