Run Time: As long as you are moving!
The Marwi Front Generator Headlight is the ultimate commuting headlight. It will light the darkest road and NEVER needs batteries! The only down side to this light is that it goes off when you stop. It would be prudent to also use a cheapo (the CatEye HL-330 for $9.99) headlight that you turn on when you come to a stop. The generator can be pulled away from the wheel to a locked positon for daytime riding.
Bulb: 2.4 watts
Battery: 6 volt generator
