There are several manafacturers that make wireless light bars and individual wireless lights. Wreckers have been using such set ups for several years. i ordered the cheapest set up by Blazar Manafacturing that ran $129.00. Units can go up to over $600 offering more durability, etc. The lights afix to the vehicle with 90 lb rated magnets, and each light takes 4 double A batteries. the transmitter utilizes a four blade plug and I simply use the PC's 7 lug plug with and adapter that goes to a regular 4 blade. You merely plug the very samll transmitter in and then situate it somehere (hitch/steel) that allows for the signal to get to the back of the toad vehicle, I think the signal will go like 50'. The lights are LED, very bright and all fuctuions have atleast this far worked flawlessly. what is nice is I can use the lights on my utility trailler, etc. as well. I did order some DiamondShield material that I cut into 5" circles and placed each on the roof of the Cherokee, the lights have a padded material over the magnets but I know dirt and movement will get under and i did not want any scratching. Tractor Supply, AWDirect, and others all have wireless light products. i think I should have spent a little more money and actaully gotten a light bar that would have absoutely no wires flapping around between the two light bases. I really like the idea of no corrosions, cutting in to the tail light housing, etc. Time will tell. thanks
