This was the only light that would fit the Kustom Werks quickbob rear fender that I bought for my 95 sportster. I had to open up the slots on the fender about a 1/16" on each inside slot to make it work but that isn't the fault of the light. The wiring is simple. Ground to ground then the other 2 don't matter as they are just in and out for power. The light looks great and functions great. I have only had it on for 2 weeks but have no reason to believe it won't continue for work as it does now.
