I’ve noticed that newer green lights on traffic signals are colored an annoyingly grassy-bright shade of green. They look as if they’re made up of a number of little light-cells clustered together. The older green lights have a kind of cool, minty hue, and are somewhat eye-like in being (I think) a central light with a reflective backing and tinted lens. Although their surfaces are mottled, kind of like a football, they’re also curved-looking, organic. The new ones look harsh, overbright.

If any signal needs to be brighter, it’s red. People don’t have problems seeing green lights!

    I always thought it was to avoid the whole light failing if the bulb blew, so if one of the LEDs (I assume they’re LEDs) was faulty, most the light would still be there.
