I am up this early on Saturday becasue, Friday AM I did not ride. I had to be to work on time because I picked up a class of students, it was raining and I had a blackburn 3.0 light and my other light (worthless) burned out last week. Anyway I cant see very well and was afraid I would bust my wheel in a chuck hole or something and be late. Soon as I got off work I headed for the LBS. I bought a Night rider light. I wanna go for a ride before daylight. Last night in my dark garage it looked 10x as bright as my blackburn. THis one seems easy to use and recharge, I just hope it last a while.
