Billboards and other electronic signs use apparent motion to simulate moving text by flashing lights on and off as if the text is moving.. The term illusory motion, or motion illusion or apparent motion, refers to any optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position.

A strobe light or stroboscopic lamp, commonly called a strobe, is a device used to produce regular flashes of light. It is one of a number of devices that can be used as a stroboscope . The word originated from the Ancient Greek στρόβος ( stróbos ), meaning "act of whirling".
A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary. It consists of either a rotating disk with slots or holes or a lamp such as a flashtube which produces brief repetitive flashes of light.
Intentional light variations are applied for warning, signalling (e.g. traffic-light signalling, flashing aviation light signals), entertainment (like stage lighting) with the purpose that flicker is perceived by people. Generally, the light output of lighting equipment may also have residual unintentional light level modulations due to the ...
Strobe lights are flashing white lights on the furthest left, right and, on larger aircraft and some smaller ones, back points of an aircraft. They are the brightest lights on the aircraft, and are used to signal that an aircraft is entering or approaching an active runway, or for visibility in dark, clear sky.
In some parts of the US, a few traffic lights have slowly flashing white strobe lights superimposed on the center of the red light, which are activated when the red light itself is illuminated. These are common on highways with few traffic signals, in high-traffic, and/or high-speed areas (where drivers running red lights are a major problem ...

Modeling light — A continuous light that illuminates the subject and aids the photographer in composing the picture. Power connector — The receptacle for the power cord. Power switch — A switch to turn the monolight on and off. Slave sensor — A sensor that detects the flashes of other strobes and triggers the strobe of which it is a part.
