if fuses are fine and bulbs, then take tail light covers off and verify connections and verify that you have power going to them with a volt meter. if you have power back there then more than likely you have a ground issue.

I have a junction box that all my light wires back there on the tailboard(flatbed) and the two plugs for my gn plug and bumper pull rv plugs run into. I temporarily have run a wire to the taillight stud to give them power when i flip the switch. Where is the taillight ground? They work fine with the jumper, but when i turn on the actual headlight switch they dont power up
