I'll defer to
mechBgon's beamshot links which include the SuperFlash and Radbot 1000 that are our best blinkies, and the DiNotte 140R, 300R and the Ultrafire red flashlight that are our "be-seen" tail lights. The Ultrafire gave us an inexpensive, third "be-seen" tail light that I happen to have a good way to mount on one bike.

Makes sense. There's also been a recommendation to use a skewer extension to mount a flashlight next to the rear hub, so the flashlight can be pointed back but be farther from eye level.
