Adapter to Allow 2019 Mercedes GLS450 to Tow Trailer with LED Taillights

Published 11/06/2018

Question:

Hi, I have purchased a new Mercedes GLS450 suv and the vehicle is not lighting up any of my LED lights on my 20’ ez hauler enclosed trailer. Can you please point me to the right direction? Thank you.

Newer European vehicles like your 2019 Mercedes GLS450 notoriously don't like trailers with LED taillights. For these situations the solution is the 7-way adapter part # 20142 which has diodes built into it so that the vehicle thinks a trailer with standard lights is being used.
