(3R sectors)

White from 211 to 018, 049 to 087 and 145 to 184, red in intervening sectors. RACON C ( ).

The range for light through the red sectors is 13nm.

The structure originally had a balcony that encircled the enclosed, circular light keeper's quarters. The balcony and its railing were later removed.

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 60 second period, the light is on for less than 30 then off for more than 30.

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.
