Thank you, dcrowell. The blog seems very informative. I am reviewing it now. I had no idea that bulbs could burn out at high speeds. That's not good at all, especially if it happens during downhill rides. The hub dynamo would eventually be the way to go.

Also, are there any gizmos to charge up any USB devices? (phone/cams/etc).

I was looking at this item, sound to good to be true...
