Bulb-Out Sensor in 2015 Mercedes ML350 Goes Off When Towing Trailer w/ LED Taillights
Published 08/08/2015
Question:
I have a new Mercedes ML 350 2015 and although the adapter for the trailer lights from my GMC fits it doesnt work and I get warning messages that the tailight is out. I have heard of an issue with German cars and the lights on trailers not drawing enough. Is there a adapter to make it work? 7 way to 4 way? Thanks

I'm assuming your trailer has LED lights. What's going on is that the bulb-out sensors aren't sensing enough power draw through the taillight circuits. The system thinks you have a burned out bulb, so it warns you about it.
We do indeed have the adapter you're looking for, part # C35FR. This is a 7-way to 4 or 5 pole trailer connector adapter that has load resistors installed in it. The resistors fool the bulb out sensor in the vehicle.
