Question:

I have a 2012 Arctic Fox 5th wheel with Bargman tail lights. One side will not flash with turn signal or hazard. Upon removal of lens it looks as though this is a sealed unit and the whole assembly needs replaced. Is that correct?

It's possible the lights need to be replaced but I'd first check the wiring as that's more than likely the issue. You can use a circuit tester like part # PTW2993 to verify that the correct voltage is making it to the light assemblies when the taillight functions are applied and if that check out it's most likely the ground which can be easily fixed by running a jumper wire from it to the main ground of the trailer wiring.

I also attached a couple help articles on trailer wiring troubleshooting for you to check out as well.
