The VRB-25 is a lighthouse optical system designed and built by Vega Industries Ltd. in Porirua, New Zealand. It was originally designed in 1993–95 with the assistance of the United States Coast Guard to meet USCG requirements for a robust mechanism requiring minimum maintenance. It has become the Coast Guard's standard 12 volt rotating beacon. The company's literature says there are more than 400 installations worldwide. More than a quarter of the active lighthouses in Maine have one installed.

Boon Island Light is located on the 300-by-700-foot Boon Island off the southern coast of Maine, United States, near Cape Neddick. Boon Island Light has the distinction of being the tallest lighthouse in both Maine and New England at 133 feet (41 m). The lighthouse has a focal plane at 137 feet (42 m) above mean high water. The light's beacon flashes white every 5 seconds.
