Looked around for quite a while before deciding to put two of these on the bike 2 seasons ago. Huge difference in visibility. I am using the 50 watt floods and am happy with that decision. The instructions were a bit sketchy and the fact that I have a shop manual with electrical schematic was a big help. I put the relay switch on the accessory line instead of the headlight line and am pleased with that decision as well. The fit was perfect.
