The characteristic flashing pattern for the light is four one-second flashes every ten seconds. It has become the symbol for Oak Island and can be seen on many of the souvenirs sold there.
The top 52 feet of the lighthouse are black; the middle 50 feet are white, while the bottom 40 feet are grey. The final 11 ft. are the aluminum and glass light enclosure. These colors are not painted on the structure, having instead been mixed into the concrete at the time the tower was constructed.
