Re: ac or dc
I have heard that the white wire puts out a very noisy AC voltage. I would not recommend hooking it up directly to a battery. I haven't tried anything yet but I suspect you would need to put a rectifier on the output and a voltage regulator in line before using it to charge a battery. You might be better off just springing for one of the brighter LED systems available for bikes.
If it can't be broken I'll find a way!
I'm not lost, I'm exploring!
