Like hopperja said, I found the light to be "adequate". Nothing impressive, but for under 20 bucks, you get what you paid for. I test it today for a short 5 miler in pitch black roads and I could see where I was going, avoided a few pebbels, some pot holes and a snake. I also got a friend to ride it towards me while I was riding his bike, to test if it was "too bright" as to impair vision of other riders. It obiously doesn't, which is a good thing if I ever get to use it on the MUP.

I'll eventually get something better, but for now, it does the job. If/when I get something better, I'll keep it as a backup, or a lower power light for MUP riding.

and to localhost: LOL I never noticed... it's a factory label... will have to ask trek engineers about it's purpose.
