I had some tire trouble on the way home the other night. During the flat-changing process, I tossed the Tirefly into the outside pocket of my pannier; the one in which I keep keys-wallet-cell phone-other assorted stuff I use daily.
I now have replaced the torn tire, but haven't put the Tirefly back on. I notice when I'm rummaging the pannier pocket looking for something, the Tirefly lights up in there. The strobing is slightly annoying, but the yellow light is welcome help in spotting whatever I'm looking for.
