For me the only proper way of lighting a bicycle is with a rechargeable
battery. The LEDs get clean DC and the battery can be recharged from any
source, even a pulsating one. That way the lights will not dim to "stand
light" or go out when waiting at a traffic light. Why should bicycle
lighting be inferior to car lighting?

What F-ing world do you live in where you recharge the lights on your car? It must be a pretty F-ed up world. On all the cars I have driven, you turn the switch and the lights come on. There ain't no recharging the car lights. Rechargeable lights and batteries. Why not just duct tape a flashlight to your bars. Then you can stop at any convenience store and buy some new D batteries and ride forever.


I think Joerg meant that the automobile current from a
12~14VAC alternator source gets run through a diode bride
and then (as switched by the regulator) through a lead-acid
pile.

It's a lot of hardware for a bicycle I agree, but Joerg's
seems to work for Joerg's values of performance and
efficiency. Frank & I prefer a simple 6VAC tire drive dynamo
and others extoll USB-LiIon sets or hub dynamos. World's a
big place and people have their own criteria, which are
often inscrutable.

I'm a hub dynamo kind of guy. It just works. Don't even have to remember to flip the roller against the tire. As long as the front tire is rolling forward, it works. I agree with this "their own criteria, which are often inscrutable."
