I have no reverse ligths no brake lights or running lights. I replaced the headlight switch, bulbs, brake switch, and reverse switch, fuses are good. And im running out of ideas please helps

I would start checking the wire harness maybe it's just unplugged. Follow the harness back from the rear light sockets check at each connector for power and ground to find where your you lose it at.

Nothing is unplugged. It ligths up in reverse the breaks ligths do but no reverse ligths but once out of R they dont work at all
