Lazaretto Cairn Lighthouse guides vessels westward on their approach to Kingston Harbour.[2] It appears to be a historic daybeacon converted to a lighted aid.[2] It is located on a bluff on the west side of the harbour entrance, opposite Port Royal.[2] It provides the rear light of the Rackhams Cay Range.[2] Its ground is maintained by the Port Authority of Jamaica, an agency of the Ministry of Transport and Works.[2]
