I commuted by bicycle for 3 years, from March of 1999 to August 2002. I've made many mistakes and I've learned a lot. I hope to pass on some of this knowledge to beginners and share with the experts. I also provide my old commuting statistics to the world, for your curiousity. Additionally, I have made a homebrew headlight and have included detailed plans, so you can make your own or just compare to what you've got.
