years ago, maybe over 40 years, Melbourne switched all the street lights to an orangey colour , ostensibly to make it safer driving in fog

then when I came back to Oz over ten years ago I noticed all the lights had changed to white again, led bulbs I think , but higher luminosity

In old cars we had to turn the headlights off cos they'd light up the fog. The fog lights down low are supposed to be under the fog.
