This sounds like an issue with the trailer wiring.

The first thing to check is the grounding on the trailer. Make sure the ground wire has a clean connection to the trailer's frame. Any corrosion or buildup on the connection point can dampen the power going to the trailer's lights. Also, check each of the trailer light grounds by opening them. They need to have a clean connection to the trailer's frame as well. If you find any corrosion, paint, or rust at any of these points, then clean the area or move the connections to a more suitable area.

If everything is clean and there are still issues with the lights, then trace each of the wires along the trailer and look for any pinch points, cut wires, or frayed wires. Should there be any, then consider replacing the wiring.
