Flasher mechanism

Flasher mechanism is a system or device that turns lights on and off repeatedly in a flashing pattern. In aviation, this mechanism is often used in warning lights, navigation lights, or airport runway lights to make them more visible and draw attention. The flashing light helps pilots and ground crews easily spot important signals or obstacles.

For example, the strobe lights on the wings of an airplane or the flashing lights on an airport runway use a flasher mechanism.
