First thing to check is to verify that 12 volts are making it to the light assemblies with a circuit tester like part # PTW2993. Next you'll need to make sure the lights are grounding properly. The issue is between either the power or the ground for the lights. Most likely the ground though as that is the more common problem. The part # MCL44AB has a black power wire and a white ground wire. Make sure the connection for both of these is solid. If the ground is an issue you can try running the ground wires back to the main ground of the trailer to see if that helps.
