peregrine: i ride on lighted urban streets so my lights are just the to-be-seen kind available at mec without too much complication - they wouldn't give me any see-by power at all, i don't think. i have a 4-way light up front with led/incandescent bulbs and a white mec 'turtle' led on the helmet. i keep them both on 'blink' mode, and never use the incandescent. a 4-bulb red blinkie on the seatpost and another on the back of the helmet. then inch-wide reflective tape on me, my bike, and the bag i carry. there's a store near me that sells it by the metre, and just about every piece of bike-specific clothing i have is plastered with it. i have long strips of it going the full length of my rain pants alongside the zippers, a strip across the knuckles of each glove, more on the helmet. . . you probably get the picture. i really like having it on my gloves; it really seems to help with getting your hand signals seen as well as with frontal visibility.

i've been coming home in full dark for a couple of months now, and really had all the space i could want from cars. so far, anyway.
