Review on Curt 57003 LED-Compatible 7-Way RV Blade Trailer Wiring Adapter for Vehicle-Side by Jose Mcdaniel

After doing an electrical repair on my ML320 taillights I had a big problem with RV lights not working. This led to months of frustration where the lights worked one week but not the next (partly due to a faulty SAM module). Finally, one of the mechanics asked if the camper had LED lights and recommended an adapter. Apparently there is an issue with some German vehicles and trailer LED lights. Since then we have been using this adapter and have had no more problems. Even when towing in heavy rain. In fact, it worked even when the taillights weren't working properly (bad module).
