unfortunately they never are. Brightness-adjusted, that is. Everyone installing lighting fixtures these days believes they must be daylight-level bright. The only ghosts you see are afterimages if you happen to look straight at the streetlamp ...
(I find it odd; dark-adapted eyes see a lot, including movement in shadows or low-contrast obstacles - after all, our bodies know how to see well at moonlight levels of illumination. Why are we so keen to kill this ability?)
Because
1) Humans night vision is significantly worse than your regular vision. Low light would cause more accidents, eg.
2) The elderly have pretty terrible night vision. Your idea would exclude them from half the day.
The elderly don't generally go to the park for a midnight stroll. Nighttime is the realm of the young.
What? When sunset is at 5pm you want to lock the elderly up in their homes? What about those that have trouble sleeping, like many do? Or those that wake up before sunrise?
This is the kind of thinking that leads to totally inaccessible cities.
