Yup -- when I commuted in west Los Angeles I supplemented my front and rear generator-driven lights with one of those on my left arm and one on my left leg. I would like to see them reinvented with smaller batteries and LEDs although some of today's LED bands are pretty good substitutes. I also used lots of Scotch reflective tape and bright orange tape.
Seeing how well LEDs outperform all previous lighting systems makes me proud to be a semiconductor industry veteran.
