I have 220 lumen Terralux flashlight that runs on 2 rechargeable AAs. I get at least an hour of high power beam from one set of batteries. That's two dark commutes worth for me. It is my primary "see where I'm going" light. I also have a PB 1 LED blinkie in my handlebars and a PB Spok on my helmet, both usually set to blink "to be seen". They're a great way to go lighting-wise on a budget.

I know of people who just use TwoFish lockblocks on their helmet with a flashlight. It can be done. Either the Bikeblock or the flashlight holder depending on how you need to orient the block to the vents, etc., on your helmet. Probably depends some on what helmet you use...
I think some people have used Livestrong bracelets and the like as well.
