Will Tow Ready Wiring Adapter # TR20141 Work With Trailers Using LED or Incandescent Lighting

Question:

I have a 2007 X3 with a factory hitch. I will utilize a couple of different trailers from time to time. One has LED lighting and the other has incandescent lighting. Will this module work for both type of lights? I assume that this module will fix the issue with LED lights and the flashing, right?

Expert Reply:

The Tow Ready Trailer Wiring Adapter, part # TR20141, you have referenced will work with both incandescent or LED lights on a trailer. This adapter is designed to be used on vehicles with incandescent lights towing a trailer with LED lights.

The Lamp Out Warning Module on your BMW X3 is a feature that lets you know of a bulb that is burned out on your vehicle. It also passes through the trailer wiring. When towing with a trailer that has LED lights, which require less power then incandescent lights, it will sense that the lights on the trailer are out and give the lamp out warning. The Tow Ready adapter has inline resistors that keep the vehicle computer from sensing a lamp out at the trailer connection.

This adapter will plug into a 7-Way on your tow vehicle and allow you to plug in either a 4-Way or a 5-Way connector on a trailer.
