I mentioned upthread using my B&M halogen headlight on dusk-to-dawn
brevets and PBP. I saw quite well with that light, but most of those
rides were far out on rural roads with very little ambient light or
light pollution. In town that light is washed out on the road by
street lights, car headlights, etc. Technically the road is just as
brightly illuminated by the lamp as in the country, but the greater
ambient light in town impairs night vision by comparison to a very
dark countryside. Thus the light seems less effective. And since
we're seeing with our eyeballs and not spot meters, it is less
effective in town.


I get good benefit out of a cycling cap with a brim, including at
night. Similarly, I use the visors in my car a lot, including at dusk.
It really helps my night vision to shade my eyes from street lights,
the brighter night sky due to the last bits of sunlight or light
pollution. And of course, if some idiot refuses to dim his high beams,
these things are godsends.


I have never thought of doing that and will try it out.

(About idiots: Yesterday I was in my car, stopped at a red light at
about 9 AM. The pickup truck lawn service guy facing me had his bright
headlights on, glaring in my eyes. I blinked my headlights once, then
once again, trying to get him to dim his lights. His response? He
turned on the off-road light bar on the roof of his cab. There's no
shortage of idiots.)


That's not idiocy, that's aggression. Well, the two are often closely
related so maybe it was idiocy...
