It’s only recently, with LEDs, that really practical hi-power bike lights have become available, especially at a reasonable price.
I hadn’t thought about that. LEDs ought to make a big difference. I ride horses now instead of bikes, but I don’t ride them at night on roads.. Unlike a bicycle, a 1000 lb horse will sometimes get ideas of its own about where to go and why, and my horse’s judgment is even worse than mine!
