Do your turn signals work with the lights off or in these 3 conditions??

First thing check for grounds at all the light fixtures, check that the bed is grounded to the frame, the body is grounded to the engine, the engine is grounded to the battery.

Yes, also check all your bulbs. They can do crazy things if broken, or installed backwards.

Well now all my lights work I'm guessing there could be a lose connection or something
