In order to see. I'm close to night blind.

I've been thinking about, In order to prevent theft, a lighting system fully contained in handlebars or something along those lines. My plan had something like 2 LEDs on each side and a halogen in the center (would require a custom stem as well). Could be pretty slick if done right.

There is a huge thread over at MTBR.com forums on DIY (do it yourself) lights.

There's more info there than I've seen anywhere. Give it a shot.
