I commute at night a lot, and I've always made sure to have a bright light. My current bikes sport a DiNotte 600 and a DiNotte 200L, respectively. Good lights, but dealing with battery charging and upkeep is a pain.

The new LED dynamo lights are as bright as high-end battery lights were a few years ago, and the German lights have well-engineered beams, making them more useful on the road than battery LEDs, or so I've been told. And the price has dropped considerably, too.

Therefore, I'm considering making the leap to a dynamo. What's your setup?
