And I'll bet that my single $28 Terralux 2 x AA LED flashlight mounted on my helmet with a rubber band throws out more light than your 1993 Niterider setup. Plus, it has no wires. Plus, you can run one on the bars, and the helmet. And, it drops into your pocket instantly when you're done riding.

Light technology has improved a LOT in the past few years. Current-gen LEDs are amazing for output, price, and efficiency. If you really want to use lights nowadays, check out that Terralux light, or the Magicshine for uber-lumens for <$100.
