Great minds think alike. A lightweight racing bike for weekend fun rides can get a battery light attached to the handlebar. A bike that gets frequent utilitarian use should have dyno lights. I have trouble convincing people if they don't experience it for themselves. Yet Europeans wouldn't ride without them, and for good reason, I think. The lights have gotten so good lately, and decent ones are not more expensive than battery lights. My housemate took my commuter bike out one night and was so impressed, he is going to do the same with his bike.

Sorry if you've seen this already, but here is my article on how I built my system. I am extremely pleased with it. Soon I'll be putting dyno lights on my Raleigh Twenty.
