Lights and Generators?

[CruisinOCMD]

Has anyone used the headlight systems that use magnets to generate electricity? If so how well do they work?

Something like this Amazon.com: Reelight SL500 Front Headlight: Sports & Outdoors

Not bright enough and the generators r not desing to go at 30 m/h so they break down soon after installed. Thats my experience with it.

Maybe a Kubota dynamo? 10 amps 12 volt the whole thing rotates,.could friction drive it, add a small gellcell batt and small tympanium regulator.

putting a bigger wheel on it slows down the rpm. Then you get long life and bright lights.
