The light, which flashes white every five seconds, also was turned back on in 1989, as a private aid to navigation.
Since the early 1990s, under a long-term lease from the national park, the house has been the private summer home for a university professor and his family, who spent three years renovating it, and who have agreed to pay for its maintenance and repairs.
The lighthouse is best viewed from various tour boats, or the mailboat to the Cranberry Islands.
