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.

Nice and bright, different flash settings, great visibility, mounting needs a little improvement. If there's one piece of advice I can give is check your seat-post before using this light. The seat-post is the ideal spot for placing this since you want the flashing to be as high as possible. Unfortunately my Raleigh SC40 has a seat shock post which is far too wide to use the mounting :( The rear forks also do not accomodate the mounting so there are precious few places this can be done. Unfurtunately, this means my flashing light is relegated to operate from a plastic bag dangling from my seat :(

This rear light can be seen for BLOCKS!! A great feature is the clip--it can be either clipped onto its seat post attachment or to a piece of clothing, if you walk at night. Battery life on blink (which is IMO much safer than constantly on) is weeks, if not months. Small enough to easily fit into a pocket, if you need to take it with.

With today's cheap electronics and LED technology it's trivial to make a super bright bike tail light. What you are really paying for here is the housing and mounting bracket.

I bought four of these when there was a blowout sale at REI. They're not terrible as other people have mentioned (cheap, small, light, bright, cheap, long running, clip for clothes, cheap, and did I mention, cheap?)

What I don't like is that the light snaps together - this is not unusual but the plastic on mine are thin enough that dropping the light onto a hard surface means you might be chasing the batteries on your hands and knees. Also, it's the plastic on the mount/clamp isn't very sturdy and if you put it on a mountain bike, it will need to be adjusted after every hard bump. Basically the plastic is so thin that you can't really tighten the adjustment screw sufficiently to keep it from slipping.

Do a search here at Amazon or the other online bike retailers - it appears you can definitely do better for the same price or even get something better for less!

Cateye makes top notch stuff, and it appears they have one which is the same price. (LD-130) I ended up with a more expensive Cateye tail light LD1100 and do not regret the extra $20 I paid for it.

Princeton Tec, Marwi, Blackburn and Topeak make good stuff - not as good as Cateye but certainly better than this.

Ride safe! Be seen!

This is a great product for the money. The mount was a cinch to install on the seat post of my bike and took only about 10 minutes. It comes without instructions, and I was a little puzzled at first as to how to install the batteries. That was a minor hurdle and certainly no reason to rate the light down at all. It was a simple matter of pulling the red lens cover away from the black part. It takes a little effort, and I was afraid of breaking it. However, it proved to be up to the task so don't be too worried about that--you should be able to do it with just your hands easily enough. I can't speak to the battery life at this point, but the light is BRIGHT! When I held it at arms length I was seeing spots afterwards. A driver would have to be asleep at the wheel not to notice me.

I found this on the street after it came off somebody's bike. It has flown off my bike once, luckily I heard it hit. Use some rubber bands or stretchy tape to help secure it to seat bag loop.

Not as sophisticated as the super flash models, but not bad at much less cost. Less likely to get stolen too. But, if you want the best get a super flash.

All tail lights should be tested and alignment checked before leaving the house. Alignment is critical and sloppy installation can degrade performance of lights by 90%.
