Here's actually an interesting question for those of you that don't run redundant lighting systems. What do you do if you lose, break, or have a light stolen, or unexpectedly run out of batteries? I've popped into a corner store to buy batteries before but lights are harder to pick up in a pinch. Do you just ride home dark?

I ask because my superflash was stolen last night after midnight, and so I rode home tail-lightless. I didn't feel too nervous (although slightly) as I had a reflective vest, rear reflector and reflective pannier, unlike the totally black totally reflectiveless lightless riders that seem to keep living around downtown Toronto. And a mirror, to see any headlights approaching too closely

Hoping someone really needed that light rather than more likely a drunk bike-less idiot that thought it was fun to blink it at others.
