Tried And Liked:

- Blackburn Flea USB Lights: Lights use rechargeable batteries that power up off your computer's USB drive via a small, included charger. Front and rear lights have 4 very intense LEDs and several flashing modes. Probably not bright enough for a dark commute, but I felt confident that I was being seen on my commute through Manhattan. The Velcro straps that fasten the lights to the bike have little strips of rubber that are supposed to prevent the lights from sliding around, but they rubbed off after a short time; nevertheless, I don't feel that it caused any problems for me. Available with various combinations of USB charger, solar charger, charger that sucks juice from loose batteries, rear, black front, and color front lights.
