After 1969, the Coast Guard removed lighting equipment from the original buildings and replaced them with a single directional light on the beach. In 1990, the Ridges Sanctuary took possession of the buildings and began restoring them; this was completed during the 1990s, when both buildings were rewired to supply electricity to the lamps. A skeleton tower, which was listed in Volume VII of the United States Coast Guard light list, provided shipping guidance until 2015, when the original range lights were updated with modern LED lamps and brought back online.
