Question:
Looking at an LED tail light - it says it comes with 3 wires - on my left of the trailer it has the yellow for stop and turn and brown for running - so how do I match up to the 3 wire LED? And then for a clearance light - my trailer only needs one wire, brown, for running lights - so how does this match up?? And does each LED need to be grounded separately??

Expert Reply:
When it comes to wiring an LED taillight like the Sealed 4" Round LED Trailer Stop, Turn and Tail Light # STL42RB with Pigtail Harness, # A45PB, the red wire is for stop and turn, the black for running lights, and the white wire will need to be attached to a clean and corrosion free bare metal surface on the trailer.
As for a clearance light having two wires like the Rectangular LED Trailer Clearance and Side Marker Light, # MCL32AB, you will ground the white wire and connect the black wire to your running lights.
So to answer your question, yes, you will want to ground each taillight separately.
