In regards to the Incandescent RV Tail Light part # RVST60, the white wire is for the ground, the black wire is for the tail light, and the green wire is for the right hand stop/turn signal. The wires on your trailer should be white for ground, brown for tail light, and green for right hand stop/turn signal. However, in order to be certain you will need to test for function with a circuit tester. In order to do this you will need to isolate the three wires you have on the trailer, apply one of the signal lamps in the vehicle, and then probe each of the wires. The wire that illuminates the circuit tester is responsible for the signal you activated in the vehicle.
