With weird, illogical problems like this on trailer wiring the fix is almost always improving the grounding of the trailer wiring. So make sure the ground strap that runs from the connector to the trailer frame is connected to a clean metal surface and also make sure the light assembly grounds are connected to a clean metal surface as well.
I also attached a link to an article that covers trailer wiring troubleshooting for you to check out as well.
