Sledder4life, I bought them (8)as a kit with switch,fuse block and added some heavier wire. they are led light pods that have 4 leds in each one, the housing has two holes which I used stainless bolts and lock tighted the nuts. I have two on each running board and each shock well and two under the hood. they just get wired into a "hot" lead when sled is running (use a test light). I got them through Firelights.com but recently tried to order more from them, but after a month went by no product, got my $ back and heard owner had bad accident? google led courtesy lights you will find other vendors, I just found same led pod but with 6 leds I wished I had them for even brighter look!
