Have you ever been launching your boat in the dark and could not see how close to dock you are? I got tired of getting out of truck and checking how close I was so I would not hit and ruin my fiberglass fender. I wanted something that was not to bright as to blind other anglers at tournament. I decided to mount a livewell light to my fender and spliced in to backup light.light.jpg it gives just enough light and does not blind anglers on shore.
