Dodging debris on a debris-strewn highway shoulder was part of the daily routine. Spotting it from long range, with plenty of time to avoid it, was the job of that super-thrower flashlight. Actually the photo I posted doesn't show what I described, that's the previous iteration using a TwoFish block on a Minoura Besso... sorry for the goof-up!
It's not easy to do justice to bike lights with a digital camera, but this is the Dereelight DBS V2 on a secondary highway. No exaggeration to say it had an effective range of over 100 meters in a dark environment, if it could be kept on-target.
