The trafick light was invented in 1993 because cars are not takeing turns when to go and getting
car accedents. The first gas lit traffic light was installed in 1868 in london. They picked the colors
red green and orange cause there is a color code. In the typical sequence of color phases. The green
light allows the traffic to proceed in the derection denoted. The yellow light provides warning that
the signal will be changing from green to red. The red signal prohibits any traffic from proceeding.
They picked tho's colors because the red is usally means bad and green means good and yellow
means kinda bad.
