I agree that the technology is changing rapidly. It's amazing how much prices have come down in the past few years. You can now buy a "see by" light for <$100.

I ordered this light just this week for commuting. It arrived yesterday and I haven't had a real after-dark commute with it yet, but I zoomed around the neighborhood a little last night and I was very pleased. I had retina surgery recently and my night vision is greatly reduced, but I had enough light that I'm not worried about riding home in the dark now.
