I've run into an issue with my new boat trailer. It is a 2012 BoatMate trailer for my Super Air Nautique 230. Since the trailer has LED lights, whenever I hook it up to my SUV (Mercedes ML) and I turn on the headlights all the lights on the trailer start flashing. If I press the brake pedal all lights work as expected. As soon as I let go of the brake pedal the lights start flashing again.
I've contacted BoatMate and they say its a vehicle issue. I've contacted my mechanic at the local dealership and he says they've never had that issue. I've called e trailer.com to see if they have a variant of the following adapter for my vehicle with no luck:
The issue is that the trailer has a 7 pin adapter tied to the wiring harness so it doesn't require a 4-pin -> 7-pin adapter like most older trailers do (at least that's how my previous Dorsey trailer was). When I spoke to the boat dealership, they said people with Land Rovers have run into this issue but they didn't have a fix readily available.
Any help is greatly appreciated!
