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 40 second period, the light is on for less than 20 then off for more than 20.

Puerto San Juan Light was listed on the National Register of Historic Places on Oct. 22, 1981, reference number 81000693.
