Has anyone built a DIY front bicycle light?

Hard to justify with the modern 5-LED units in relatively rugged water resistant housings. But I have installed voltage regulators and used external gel cells (in a seat pack) to power them. I had an old DIY LED tail light, which was a grid of traffic light LEDs on a perf board. But eventually, the road grime and salt corrode everything and it gets unreliable.

There's designs for microcontroller-based halogen lamp controllers at Lightbrain and a simpler one using the 16F84 complete with PCB layout... Freeware Controller. This'll give you 1/3, 1/2, and full power.
