Expert Reply:
The brown wire for your trailer wiring should be for the running lights while the white wire should be for ground. Typically clearance lights use black for power and white for ground, like part # MCL32AB, but in the case of black and red wiring the black is typically ground while the red is for power.
This can vary between products but you can simply touch the black power from the light to the white wire from the trailer wiring and then the red wire to your brown wire. If that doesn't work then simply reverse the wiring and your light should work just fine.
