Did I miss something? Why can't magnet lights be used? Just run flat 4 trailer wiring from the trunk, thru the passenger area, out the driver door, under the hood at the windshield and out the front of the hood at the grill and plug into the flat 4 connector. I tow 2 different vehicles, Chevy tracker and Pontiac Sunfire convertible. 16 years of towing and no problems. Sorry, 1 problem, 1 light, LED , quit working and had to be replaced.
