It is located on the westerly point of Battle Island, {{convert|28.5|mi|km}} east-northeast from Lamb Island Light. It was built as a white light, visible for {{convert|18|mi|km}} in clear weather. When built, it operated as a bright flash, four-second interval, bright flash, four-second interval, and then bright flash, 16-second interval, with a concurrent lower-strength light operating at 12-seconds constant/ 12 seconds eclipsed. Its fog horn (originally referred to as a "fog diaphone") blasted for 3½ seconds and was then silent for 26½ seconds.[2] The lighthouse was rebuilt in 1915-16 in response to increased demand from local wood pulp carriers and commercial fishing boats.
