More light
Sep. 7th, 2009 07:09 pmI went out for another moonlit walk very late Friday, with the moon high in the clear sky. It really is amazing how much light it reflects, if you're out of the city lights and can let your eyes adapt.
Earlier, I had cycled home in the dark with my metal halide arc lamp attached to my head to light the way, and again saw that interesting and unusual phenomenon of the cautious, courteous, even deferential motorists. How often do you see that? But, as they wait to make a left turn while I'm still quite a distance from the intersection, they see only two points of light, one very bright and high, one much dimmer and low (from my auxiliary LED headlight). They really can't tell my distance, nor my speed, and, most importantly, I don't think they can even tell for sure that I'm riding a bicycle. So rather than turn in front of me, they figure it's best to wait until I'm past. Whatever it is that I am.
