How many people walk under street lights then they turn off or on?
It varies depending on the specific location and time of day. Some street lights are equipped with sensors that detect movement, causing them to turn on or off when someone walks underneath. The number of people observed walking under street lights could be influenced by factors such as weather, time of day, and the purpose of the area.
Why do street lights go out when you walk by?
