A 'flashing' light is a light in which the total duration of light in a period is shorter than the total duration of darkness and the appearances of light (flashes) are usually of equal duration. So in the 6 second period, the light is on for less than 3 then off for more than 3.

Prospect Harbor Light was listed on the National Register of Historic Places on March 14, 1988, reference number 88000151.

NOTE: Sectors of colored glass are placed in the lanterns of some lights in order to produce a system of light sectors of different colors. In general, red sectors are used to mark shoals or to warn the mariner of other obstructions to navigation or of nearby land. Such lights provide approximate bearing information, since observers may note the change of color as they cross the boundary between sectors.
