The lighthouse was constructed in 1823 and originally sat on a dike off Goat Island further south in the Bay, where the Newport Harbor Light stands today. In 1851 the lighthouse was transported to Prudence Island where it remains.

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.

Prudence Island (Sandy Point) was listed on the National Register of Historic Places on March 30, 1988, reference number 88000270.
