I was shopping for tail lights last week and decided that I wouldn't be cheap and i got the top of the line Cat Eye LED model. It has 10 LED's and is visible from the side. I had read good things on here.
It arrived today and I quickly threw the batteries on and put it under my desk (it's kind of dark there). Wow. This thing is REALLY bright. My concern is that it might actually be too bright, if you can believe that! Has anyone with this light had any complaints from drivers? I imagine it's less obnoxious if I put it on steady, but then I get less battery life!
