The light is white, red, or green depending on the direction. The lights can be seen for up to . History. The original 1886 tower has been inactive since 1925. The white, square tower was about tall with a sharply pyramidal dark maroon, metallic roof and a spire. The tower is attached to the front of a one and a half story keeper's house. The old tower and house are now a privately owned summer residence which is only accessible by boat.
