No it's a horrible idea, imagine the lights turning on and off as people pass. No!

Indeed that would be terrible, especially in dodgier areas. Not only you're advertising your position to potential attackers, but you're also less likely to see them until they're very close. I believe relatively dim, warm coloured lights are a much better idea.

  Last sentence is a fine idea, it is also possible to move toward developing a society where “potential attackers” is a thought much more distant in people’s minds.

    > it is also possible to move toward developing a society where “potential attackers” is a thought much more distant in people’s minds Amen, but alas we're not there. In any case, threats don't always come from purposeful attackers. It's useful to see animals, vehicles and bikes with no light, etc.

      >Amen, but alas we’re not there What is troublesome is that many places, that many of us probably hail from, “were there” not so long ago, and it was destroyed by duplicitous, malicious political and cultural actors. Having “safe streets” is not a pipe dream. Indeed not having them is a symptom of people trying to destroy our societies.

  You could see the attackers just as well as they see you. I meant because of the annoyance that it would create. The problem with warm lights is that they are much harder to see in the dark. Maybe dim lights around 505nm would be a better idea.

Light by definition is easier to see in the dark than it is in light as it has less light to compete with. In any case, I find warm lights much easier. Cold lights are too much sensorial information for me. In any case, street light at night shouldn't be meant to allow you to see everything like it's a sunny day. It's supposed to give you enough light that you can see your surroundings and potential threats around you. For that, warm lights should be more than enough. If you need more light clarity, light your own phone torch or something.

      I mean they need to be pretty bright to be visible at all. Notice how red leds still look dim at night, but green blue are shining in the dark room. The eye can't adapt well to dim warm light. And that is the other reason. Those would still make nights look like nights, they should look sort of moonlight like with reasonable brightness.

        I'm still unsure what you're advocating for. Dim, but cool coloured lights? That's certainly better than bright cool ones but I still find them very annoying and overstimulating at night. The only thing I can't do with dim, warm lighting is read small text from something other than a backlit screen. For everything else, it's perfectly fine. And if I do see myself having to do that, I'll just add a spot of light to what I'm trying to read, problem solved.
