Question:
Good morning, I have a 2014 Mercedes vito van. it has a 7 large round pin trailer connection. When I connect a trailer fitted with led lights nothing works but all lights work fine with a trailer fitted with normal globes Do you supply an LED adapter from 7 large round pin to 7 large round pin ?

I have a solution for you, but as far as a simple adapter like the part # 20142 that would plug into your 7-way round there isn't an option available.
Instead you would need to install load resistors on all of the taillight circuits of your trailer that have LEDs. For a pair you would want the part # DI34ZR.
