Bests & Worsts Reviews from Amazon

The purpose of any LED tail light is to make sure cars coming up behind you know you're there. The Planet Bike Blinky 3 does a fine job at that, stays put, has great battery life and doesn't cost much. You get two mounting options - a big cheap plastic clip for the seat post and a smaller clip for a rear side strut. I put mine on the seat post. In past years when I had a baby seat I would have used the side strut. You also get two settings - steady and blinking. That's the only negative in my book. I can't imagine using anything but blinking. This is pretty much a no brainer. My wife's has been through almost 8 years of abuse and has had only one battery change. I didn't think twice when it was time for my bike and my son's to get this safety enhancement. I now bike a lot during the late night. I haven't had a close call with a car coming up from my rear yet. Enough said. Update - 8 months later (6/5/09): I added a bike rack over my rear wheel and had to re-mount this because the rack's cargo obscured the seat post. Neither included mount fit the small gauge bars of the rack. I was able to use the small mounting clip by adding a small strip of black rubber (cut from an old inner tube scrap I had lying around). Because of the orientation of the rack's bars my light is now sideways. This arrangement works fine for me. I'm still on my original set of batteries and I use the light at least once a week.
