magnetic wireless toad lights.

Yes, I do use them. My dealer was very emphatic when we bought this truck new that if the wiring was disturbed with towing lights that the GM warranty for the electrics would be void. We have used this dealer for many years and he knows we tow our trucks behind the RV. I have been very satisfied with them and the batteries last well over 24 hours of continuous use, which translates to at least a month of towing use.
