All that said, I have little fear of riding without lights! 45 years in urban traffic and no serious collisions ... no collisions ever, to date. It ain't luck! You CAN prevent most collisions by riding defensively, and by not putting responsibility for your safety onto the shoulders of total strangers. I'm not telling you that, I figure you know that already. When I turn on the flasher it is so that if I wind up in an accident no one can say "see, if he had had flashers ...", but I would never suggest to someone (as has been done in this thread) that they should use flashers to prevent an accident. They do not, and cannot. Ride defensively.
