71 F100 Lights Issue
I have a 71 F100 and the all lights are working except the rear running lights
and the now the Headlights Surge. I had all working yesterday after buying
the truck and replacing the bulbs in the tail lights and now all I have on the rear
are Brake Lights and Turn Signal. Then the headlights and cab lights starting
blinking or surging. I would greatly appreciate any help on this matter.
