I went to REI this afternoon at lunch, and joined three other cyclists all staring at the light display, trying to figure out which light would illuminate the road best. So many choices! I came away with a CatEye light with a beam so bright that it hurt my eyes from across the room. It takes 4 AA batteries, but I will try rechargeables to cut the waste down. The $150-and-up lights with dedicated, built-in rechargeable batteries (on display in a locked glass case) seemed like too big of a commitment. I figure that this light, for $44, will extend my riding a little bit into the winter and allow me to start the season a little earlier too.
I also got a very glow-y fluorescent green jacket with a little bit of reflective striping on the back. It's not waterproof, but I think it will keep me dry enough in showers. And the color really stands out.
