I have heard good things about their backup lights and bought one. I opened up the package and couldnt figure how to turn it on. Come to find out the switch was missing. Took it back and got another one and opened it up right there and pushed on the switch while saying "mine didnt have one of these" and the piece of crap fell off in the floor. I realize in a pinch I could activate it with a magnet and from the looks of it that pinch occurs too often for my likeing.
