As if bike helmets aren't geeky enough. After riding home from the college after registrations and meetings in the dark this week, I was told I needed a light. I stopped in at Petrie's and checked out the goods. I ended up with the Night Rider Mi-Newt USB. It mounts anywhere, has lithium ion rechargeables, and is very light and small. I have it mounted on my old/winter helmet so I can switch bikes easily and don't have to leave it out for thieves. I still need a more powerful tail-light.
