What I like about it is that the guy does a complete headlight conversion, so that both sides light up for low beams. The angel eyes are just for looks and won't provide any real light for nighttime riding, but this guy fixed Yamaha's mistake of having only one headlight for low beam and the other headlight for high beam. Now you can have both. He also makes an HID kit with a better harness. I haven't decided how far I want to go, but I plan on getting one of these kits.
