As I may have mentioned, I work for Mercedes-Benz (not that I can afford them). We are selling tons of SUVs now and are seeing a new issue with regards to towing. Many trailers have LED lights, which seem to throw our control units into fits. They have bulb outage detection and the LEDs I take it have no resistance. We found this adapter sold through U-haul, but it is for 4-way lights.
U-Haul moving supplies: LED Light Trailer Module
Anyone know of this for 7-way? I cant seem to find one.
