http://www.youtube.com/watch?v=CLZipABHNQg&feature=related Amazon.com has best pricing but Rockymountain ATV sells them as well. You can get a Li batter pack and use it as a helmet light too. Add this to my X2 and I am ready for summertime night riding
They look like some pretty cool lights. I'll have to try them. Rick at Vision X, gives what sounds like a good price on pairs of them. So, while you're shopping around, you may want to give him a call. His prices are not posted for multiple lights: http://www.visionxonly.com/Solstice-Solo-LED-Lights-2-Inch-Square-S1100-Series.html He said not to worry about your choice of spot, flood, etc. He can either include different lenses with your order, or send other lenses as needed.
