Using these for backup/bed lights on a '21 Can Am Defender, so for me they will have fairly limited use. Had to fashion some brackets from aluminum flat stock to mount where I wanted them behind the cab and they do provide plenty of light for what I need. One light was defective out of the box (positive wire was pinched inside fixture and was shorting the conductor to ground). Contacted Nilight and they sent replacement right away. Would like to see where these could be mounted from either end (i.e.: one light mounted "upside down" from the other) so the wire leads can be routed the same way on both sides. I also bought the wiring harness that was recommended for these and the install wasn't that bad except I did have to add about two feet of wiring to reach both sides of the rear cab to make the fixture connections.These seem pretty well made but durability is yet unknown. Overall Recommended.
