Cities look much better at night on white light. I doubt we will ever go back to yellow light.

- Waterluvian 8y agoThanks for sharing. I thought it was universally agreed that white light is awful compared to yellow light. I'll have to dig deeper into this.
- jedberg 8y agoYeah that's part of the problem. People care about how the city looks vs. the health of themselves and the creatures around them.

- oldcynic 8y agoOld fogies like myself will remember that France, and much of Europe, used to require yellow headlights. The idea being that the removal of blue light reduces the likelihood of dazzle, especially in rain and fog. https://en.wikipedia.org/wiki/Selective_yellow https://en.wikipedia.org/wiki/Selective_yellow
- 21 8y agoBut apparently they are much worse in clear weather, so the new EU regulation require white lights: > Whilst yellow light improves visibility in wet or foggy conditions, it can also be harder to see with yellow lights in clear conditions. As a result, many vehicles today use yellow lights only as fog lights. > White lights are the most popular colour for the headlights of today. In many countries, headlights are no longer allowed to be yellow and must be white in colour. European regulations, for example, require all new vehicles to be manufactured with white headlights.
- oldcynic 8y agoI can only find that claim on a Powerbulbs store blog post. Current UN regs do indeed require white. Definitely not "much worse", more like simply different. They were very yellow, right out there with sodium lighting and obliterated colour acuity. So highly unlikely to be coming back. :)
- graeme 8y agoLook better, or you can see more clearly? Regardless, I'm not sure your opinion is universal. There was a pretty big protest against them in my city, Montreal, and the mayor relented.
- taneq 8y agoI actually like the sodium lights vs. the new LED lighting. LEDs are so much harsher on the eyes.
- Fnoord 8y agoThis is your opinion, not a consensus-based viewpoint (feel free to link studies though). Yellow light is more romantic and it creates melatonin. White light keeps people alert due to the blue light in it. What you prefer, depends on your interests. On the road, people need to be awake. For that purpose white light does make sense.
- 21 8y agoIt's not consensus, but there is no consensus either that yellow light is better. Here are some comments from the past, when yellow light was introduced: > Another skeptic was the Tribune’s legendary architecture critic Paul Gapp. “[Sodium vapor lamps] are more than twice as bright as the blue mercury vapor lights which they would replace and produce an artificial daylight effect whose peculiar offensiveness must be visually experienced to be understood. How can it be said?” Gapp wrote in 1974. “One looks at the eerie, ominous quality of sodium vapor illumination and thinks of the bizarre paintings of Hieronymous Bosch, the frightening futurism of Stanley Kubrick’s A Clockwork Orange, and other nightmares.” > The jaundiced weirdness of sodium light has become a vexing challenge to photographers (one filmmaker, Tenolian Bell, called it “the ugliest light known to the cinematographer”); movie cameras simulate its color by using a gel filter named Bastard Amber. Significantly, retailers have avoided inflicting the unpleasantness of sodium lights on their customers—most commercial parking lots and shopping malls use the costlier white metal halide lights.
- graeme 8y agoThis critic complains the sodium lights are like daylight. The LED lights are even more like daylight. This would appear to undermine the original poster who preferred LED.
