The current lighthouse was established and the tower was first lit in 1857. The site is on a bluff 60 feet (18 m) above Long Island Sound. The tower was automated in 1933 and is now operational. The light was deactivated from 1933 to 1990. The foundation is granite and the lighthouse is built out of granite and brick with stucco. A square tower is attached to a rectangular house. The tower is 58 feet (18 m) high with the focal plane of the light being 103 feet (31 m) above sea level. The tower is white with a black lantern and a copper dome. The light has a slow green flash every ten seconds. Horton Lighthouse on Wikipedia
