No, sodium vapor lights offer great performance in terms of contrast and visibility. Especially in bad weather conditions.

- robertlagrant 1y agoYes but that's the point: sodium vapour offers worse peripheral vision, so it could make some situations riskier.
- metalman 1y agono way, once something is into your periferal vision while in a moving car it's too late, and fact does not matter....unless it's moving realy realy fast, and then it's still too late so the real equation will involve all sorts of other inputs, like the coulor temp, and amount of direct vs reflected light, background light conditions, weather, and indivual perception of any given driver. *green light is the worst, as our eyes have the greatest sensitivity to it, and out night vision adaptation is to the black and white(muted coulor) light that is natural. current regulations are ancient, but there is no reason that a non opiniated solution cant be figured out and implimented

- quietbritishjim 1y ago> once something is into your periferal vision while in a moving car it's too late, and fact does not matter. When you're looking up in your rear view mirror, your view of the road ahead is from your peripheral vision. It most definitely does matter.

- pxc 1y agoHigher contrast isn't strictly better. Street lights where I live are deliberately sparse to limit light pollution, but this means that some of them are sometimes too bright— since the whole road isn't suffused evenly with light, very bright lights are somewhat blinding, especially to light sensitive people.
- adgjlsfhk1 1y agoLEDs are much better for this since you can get tailored light thrown by angle to even out the lighting a lot more
- pxc 1y agoThanks for sharing this! I don't know much about light and didn't realize such a thing would possible. This seems like a great technique for cities like mine that want to limit light pollution.
- mattgrice 1y agoI feel like nobody here ever drove in San Jose at night prior to 2020-ish. Because high-pressure sodium I like, LPS as in San Jose is like viewing a monochrome monitor.
