OK, after watching this video:

I think I want what this guy has. A Niteflux Red Zone 8 on the helmet, a Dinotte 400R (or maybe a Designshine) on the bike, and a pair of Trek Beacons. Looks like about $400 in taillights, maybe $500. I have a year to save up for them.
I think there's a lot to be said for having a large surface area lit rather than a point source of light. I always insist on at LEAST two lights, at night I want a constant and a flashing one.
EDIT: Ordered a Designshine DS500 taillight. Looks like it kind of fries the Dinotte 400R.
