Traffic authorities use coloured bulbs where you are? Weird.
Where I am, as far as I'm aware the colours always come from a gel in front of the lamp. Furthermore, the red lamp holder is larger than the green and amber ones.
- isostatic 7y agoDon't you have LED lights?
- microcolonel 7y agoI think they still use gels on white LEDs for many of them. I've had a look at a few that at least did that. It's possible they've switched to dedicated colour phosphors, or that the majority of them have been that way for a while. I think many of the lights here are also retrofits from incandescent traffic lights.
