3-way traffic light: History Section
Garrett Morgan invented the modern 3-way traffic light, yet it is nowhere on this page nor is it linked to his Wikipedia page. Domme2040 (talk) 18:06, 3 July 2023 (UTC)

Colorblindness
How about a mention of the fact that the most common form of colorblindness (1 in 14 males) can't distinguish between red, yellow, and green? I once read that green lights are blueish-green in order to be distinguishable for those with red-green colorblindness. Is this universal? Regulated? Since when?
I recall an anecdote where some American town with a large Irish population flipped its traffic lights, so that green was on top, but this had to be undone because the orientation of the lights must be consistent for colorblind people. But if this were the only way for them to distinguish the lights, wouldn't they have to stare at the lights rather than relying on peripheral vision?
Just a couple of things I'm curious about; and I imagine there might be more to say on the topic. SSSheridan (talk) 10:10, 23 February 2024 (UTC)
