A chase is an electrical application where strings of adjacent light bulbs cycle on and off frequently to give the illusion of lights moving along the string. With computerized lighting consoles, building chase sequences has become easier, while previously chases used mechanical means, such as a wheel with an electrified spindle which strikes electrical contacts for each circuit.

Chase lights (or chaser lights) are often associated with the marquee signs of some movie theaters, and have also been used as a common element of television game show sets.

Creating a chase effect[edit]

In order to achieve a chase "strip lights" are most often used, especially when used in "theatrical" applications.
