Usually two PBSFs. However, 95% of my commute is on MUPs, so I can get away without a tail light, as long as I'm careful on the 5% where cars are around.

Used lights for the first time last night since last winter. Noticed lots of folks had relatively weak headlights. That will change when the serious headlights come out to play. I was running only a single headlight, and even that was way more powerful than anything else I saw. When I break out the megalumen blaster, their puny lights will be completely useless.
