I wen't to the bike store and got two MARS battery powered triangle lights, man are these bright I can lust barely look at these before I go blind, major super bright. the bastards behind me are most definately going to see me. I'm thinking of getting one of thier headlights and installing it inside of the original puch headlight assy or just put one on each handle bar. Kinda prick but my ass is worth it.
