LED tail light problem
On my '37 Ford coupe I have led taillights and the brake lights and turn signals work on both tail lights until I turn on the headlights. Once the headlight switch comes on the right rear light goes dead, but the left one still works as it should. I thought it was a ground issue on that light, so I disconnected the ground wire to the right tail light, cleaned the metal surface on the frame and reconnected the ground, but nothing changed. I am at a loss. There is no socket to the light so I can't use a regular tail light bulb(1157) to check it with. I always thought an led light either worked or it didn't, any suggestions?
