Reply to comment by indy_cision in Eli5 why do traffic lights have red, yellow and green color? Why not use other colors so that even colourblind people can drive. by [deleted]
Red is at the top.
If you're close enough to a light that you have to obey it but can't distinguish the top from the bottom you've got bigger sight problems than colour blindness and probably shouldn't be driving at all.

Spoken like someone who hasn't driven in poor visibility conditions or dark enough to not see anything other than a single glowing light...
