I only use three lights: a headlamp, a front spot, and a rear tail light that I set to blink. But I do have reflective stickers on the back of my helmet and on my commuter bike, on the back fender. On my road bike, my seat bag has a reflective tape. I wear a reflective ankle band.

I use hardware store safety glasses. This sounds gross but it works: spit in them and then wipe them completely. It will keep them from fogging up.

Most of the roads I ride on have no streetlights - they are rural and full of potholes. The commuter bike does much better on winter / dark roads than my road bike, as it has better tires. I will be switching to the commuter pretty soon now that it is darker at night and in mornings. Redrhodie, the investment on the commuter of tough (but heavier) tires was worth it.
