Deer Island Light is a lighthouse in Boston Harbor in Boston, Massachusetts.
The United States Coast Guard Light List[1] description is "Red cylindrical tower; black cylindrical pier". The actual light is 53 feet (16 meters) above Mean High Water. Its alternating white and red light is visible for 11 nautical miles.
The location first had a stone beacon in 1832. The first light, a sparkplug type light was lit in 1890. It included a three story dwelling. The old light gradually deteriorated and was replaced in 1982 by a white fiberglass tower which was replaced by the present 33 foot tower in 1983.[2]
