Expert Reply:
On the light you purchased from us, the # MC48RB (Thanks for your business!), the black wire is the power wire that needs to get connected to the running light circuit of your trailer, and the white wire needs to be grounded to the frame of the trailer.
The existing wires on your trailer are not any sort of standard color, so you'll want to trace the back to see where they connect to, or can hook up the trailer to your vehicle, turn on the head lights, and use a circuit tester like # PTW2993 to see which of the two wires has power.
I'd guess the white is ground and green is power, but there's really no way to be sure without testing the wires.
