Wire Color Functions of Trailer Taillight that Use Red, White and Black Wires
Question:
I bought a set of the rear new style lights with all the red round circles for the lights. They both have a red wire -white wire-black wire. How do you hook the left signal y3llow wire and the right green signal wire so they work. Then you have the black wire. Where does that go? Then you have the white wire which I think would be the wite wire.HELP

The white wire of the light is the ground circuit, the red wire is for the running light circuit and then the black wire is for the stop/turn circuit for each side of the trailer.
On the left side the black wire gets ran to the yellow wire and then on the right to the green.
