The keeper's house is a ten-room, two-story frame structure on a stone foundation.

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.

Manitou Island Light was listed on the National Register of Historic Places on July 19, 1984, reference number 84001773.
