Expert Reply:
On your new light bar that features two wires like the Optronics # MCL922RB, the black wire should be for power, which will connect to the running light wire on the trailer. The white wire from the light bar will be for ground, which you will just need to attach to a clean, bare metal surface on the trailer frame.
