It's hard to keep up with the latest bicycle light technology these days (see my updated, yet already outdated, Bright Lights post), so I'm not even going to try. Instead, why don't you tell us, in the comments, how you're lighting up your bike these days.
UPDATE: Last January, Mountain Bike Reviews did a great job reviewing and rating bike lights. If you're shopping for lights, it's a great place to start your research.
