Single “move trailer” light problem

[Izzi-mike]

Just took delivery of new ski and the driver side lights do not work. Removed the light and it powered fine. Checked all connections at rear and and at the hitch side and everything is connected . Was told it’s an LED thing lol
Any ideas on how to troubleshoot? The dealer is 90 minutes away so I’d rather not take it back if I can avoid it . Thanks

Swap the L/R lights and see if the problem "moves". If the drivers light is moved to the passenger side and it still doesn't work, it's a bad light housing.

If it works on the passenger side, but not the driver side, you have a wiring (probably ground) problem.
