Location: Indiana | Sounds like you have a bad connection...probably the ground. Whatever you do, don't go pull all the wires out of your trailer....
If the lights were working fine with your truck before, my bet would be that it's not the truck. You can get a tester that plugs into the truck harness to see. You can also get one that plugs into the trailer harness. Or you could use a volt meter. Again, my bet is that the truck wiring is OK, but it is probably worth a look see...
Then do what the posts above said...check where the ground connects to the trailer. Make sure it connects to metal and not paint. And make sure it's not rusty.
If it's not the truck and it's not the ground wire to the trailer, then it's the trailer lights, but don't go pull all the wiring out. I made that mistake once. The wire typically doesn't go bad at all. No use waisting it. I'd say it's probably the connections to the rear tail lights. Get access to the connections and redo them. It's easy. Start with the side that's giving you the problems. Cut the wire back a 1/2 inch to get clean copper, and reconnect. And that's about it.
