Flashing Light
From Wikipedia, the free encyclopedia
Flashing Light is a rhythmic light in which the total duration of the light in each period is clearly shorter than the total duration of the darkness and in which the flashes of light are all of equal duration. (Commonly used for a single-flashing light which exhibits only single flashes which are repeated at regular intervals.). It is normally used in light signals in Lighthouses and lighted buoys. Different lighthouses have different frequencies and not all are flashing and mariners can find out which light house they are near by the characteristic of the light signal.
Other types of rhythmic lights used by lighted aids to navigation is isophase light and occulting light.
