It sounds like you have a bad ground or a short. I would recommend you check the grounds on each of the trailer lights and on the trailer connector using The Hook Probe Circuit Tester # PTW2993. The lights usually ground through the mounting studs. If there is any dirt, corrosion, or rust it could cause a bad connection. You will also want to check where the light bracket mounts to the trailer and the ground at the trailer coupler.
Using this tester will easily identify shorts in 6V, 12V, and 24V circuits, fuses, test connections, and wiring harnesses.
