CygoLite Hi-Flux LED Emitter

"You won't believe this is a LED when you fire it up for the first time. This single LED headlight cast as much light as a 10w halogen, except with white light instead of dulling yellow. The lightweight head and NiMH battery won't weight you done either. Handlebar mount with remote switch gives you the ability to change from hi to low on the fly. Up to a 6-hour runtime, means more ride time and less time charging. Includes Overnight charger."
