I DIDN'T KNOW OTHER PEOPLE WERE OBJECTUM FOR TRAFFIC LIGHTS??? BEST DAY OF MY LIFE??
traffic lights
I’m assuming the typical red-yellow-green.
Began in London, December 1868 as gas lit lanterns manually operated by traffic cops to manage horse carriages. Instead of yellow, they would gradually switch from green to red. The first light lasted a month before a gas leak blew it up and injured an officer. Still, they became commonplace globally by 1880.
First electric signal was installed in 1912, still manually operated and with only two colors with a buzzer warning of color change. The three color light was created in 1920 with a built in timer
They were computerized in the 1950s, using pressure plates to detect vehicles were waiting at lights, sometimes even how many were at light and the time they were waiting
Red = stop
Yellow/amber = slow down
Green = go
Reminder, the premise is “would a normie think it’s weird to find them attractive?” (Would they have to “hear me out?”)
