Commented on @rrhoover's RevoLights post and realized we don't have Monkey Lights here yet! I've had the M210's on my commuter bike since Christmas and it's a lot of fun. I get looks and comments during my nightly commute home (I'm usually at work past dusk) and -- the main point -- cars can see me from the side.
This shouldn't be an issue with my super-bright front light that lights up street signs 2 blocks away. But people don't pay attention. If you bike often while it's dark, I definitely suggest *some* lighting system like this.
