It is normally used in light signals in lighthouses and lighted buoys. Different lighthouses have different frequencies and not all are flashing; mariners can find out which lighthouse they are near by the characteristic of the light signal.

Other types of rhythmic lights used by lighted aids to navigation are isophase light and flashing light.
