The Coast Guard automated the Lime Kiln Light in August 1962, using photoelectric cells to turn the light on at dusk and off during daylight hours. In 1998, the drum lens was replaced with a modern optic, flashing a white light once every 10 seconds.

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 10 second period, the light is on for less than 5 then off for more than 5.
