How red yellow green colors glow in traffic signals?
That makes sense. Is there any special technology used to control the lights turning on and off?
Yes, there is. Traffic lights use a control box that is wired to each individual light. This control box sends electrical signals to turn the lights on and off in a specific order, usually red, yellow, green. The timing of these signals is controlled by a computer system that can be programmed to adjust the length of each light depending on traffic patterns and other factors.
