Helpful Expert Reply:
Typically white is ground and black is power based on standard trailer function/colors. With that said not all lights and trailer wiring follows the standard colors. You can use a circuit tester like part # PTW2993 to test the wires when the various taillight functions are applied though to verify for certain.

On this trailer the white wire is turn signal and flasher..black running lights. Always best to check with tester....never know what wires are... not always follow the colors we are use to
