Trailer light connector

We have an interstate 2014.5 and just bought a Yakima kayak trailer to haul behind it occasionally. The trailer lights are LED and the Mercedes manual says the trailer wiring connection they provide is only for incandescent. We did have to buy a converter from the 7-pin round on IS to a 4-pin flat. So trailer currently has no lights when connected. Unusual for trailer technology to be ahead of Mercedes technology.

Any solutions?

Scary ... Semis with tandem trailers are all over the place going down the road, I can't imagine a towable RV with a hitchhiker in back. No thanks.

I'd find an alternative to the tandem trailer.

But to answer your question, if the LEDs are 12vdc, what's the problem?

Interstates are motorhomes, not trailers, so there's no tandem towing happening, just a trailer towed behind a motorhome.

The problem is that an LED light doesn't have enough resistance compared to an incandescent bulb. The most likely solution is to replace the trailer lights with incandescent bulbs, or add resistors in the circuit with the LEDs to mimic the current draw of an incandescent.
