From Wikipedia, the free encyclopedia
Chasing lights is an electrical application where strings of adjacent light bulbs cycle on and off frequently to give the illusion of lights actually moving along the string. With computerized lighting consoles building chase sequences has become easier, whereas previously chases used manual means, such as a wheel with an electrified spindle which strikes electrical contacts for each circuit. The use of wheeles such as this was common for marquee lights before the advent of modern control systems, which are safer and easier to operate.
