78 F-150 TAILLIGHTS/BRAKE LIGHTS
Hi all, new owner of a 78 f-150 4X4 351m, auto.
Having wiring issues. I put the parking lights on, both sides work(rear). Step on the brakes, left brake light goes on and right side is completely out. All wires underneath look clean and I checked the ground inside the taillight housings of the bed. Anyone familiar with this. Otherwise all my lights work.
Thanks, JR

RE: 78 F-150 TAILLIGHTS/BRAKE LIGHTS
Common problem for 'both' thefront/back lamps is the 'ground tang' in the light socket to loose the ground/circuit connection.. If so, their available aftermarket with the socket and pigtail harness.. You can use a stripped wire/test leadand ground it to the bulbs brass hub, and ground the other end to the chassis ground.. If the bulb functions correctly then the socket just lost the ground...

I tested it like you said and it worked perfectly.So now I'm off to get a new socket. Btw, one of the wires moves in and out of the socket which causes the light bulb to flicker. Thanks for saving me a lot of time.
