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 4 second period, the light is on for less than 2 then off for more than 2.

Doubling Point Light was listed on the National Register of Historic Places on Jan. 21, 1988, reference number 87002271.
