Question:
I have a 2018 Audi Q5 and am planning on installing a Tekonsha Prodigy RF Wireless Trailer Brake Controller on my trailer, which has LED lights. Based on information Ive seen on this site, I know I also need to deal with the Lamp-Out issue created by the LED lights on the trailer. My question is, should I use the Curt C57003 or the TowReady 20142 solution? Do they both serve the same purpose and one is just an adapter while the other has a mounting option?

Helpful Expert Reply:
If you will be towing a trailer with LED lights then you will likely need to use an adapter with a lamp-out sensor like the Tow Ready # 20142 or Curt # C57003 that you referenced. Both of these adapters will accomplish the same task; plugging into an existing 7-Way on your Audi and providing a new 7-Way that is able to recognize the LED trailer lights. The only difference between the two items is the bracket/housing and the wire extension on the Curt # C57003. If you don't need this and want a more unassuming adapter, the Tow Ready # 20142 is the way to go.
I have attached a video demonstration for each of these adapters that you can also take a look at.
