The 1904 report of the Lighthouse Board contains the following description of Kanahena Point Light.
This is a fixed white light, composed of two ordinary kitchen lamps, estimated to be 50 feet above high water. The light is shown from a pyramidal room built at the top of a square wooden trestle tower 40 feet high. The trestle is in bad condition. The light marks a low lava spit projecting into the sea. It was erected because of wrecks on this point. There is no dwelling for keeper at the light-house. The keeper lives 3 miles away and is compelled to cross the rough trail over the lava flow.
The trestle tower was replaced in 1905 with a thirty-four-foot mast topped with a platform from which a lens lantern was displayed. Andersen remained keeper of Kanahena Light until his passing in 1910, when his wife assumed responsibility for the beacon, making the six-mile roundtrip trek each morning and night. Charles K. Akana became keeper of the light in October 1910.
Both the Makena and Kanahena Lights were discontinued in 1918 when the Hanamanioa Light was established on the southeast point of La Perouse Bay. This new tower was a pyramidal tower of reinforced concrete, like the surviving tower at Lahaina, and had a focal plane of seventy-three feet above the water. The light, run on acetylene, was automated from the beginning and a wooden derrick was built near the site to facilitate the landing of acetylene tanks and supplies at the cape.
Head Keepers: J. Andersen (1893 – 1910), Mrs. J. Andersen (1910), Charles K. Akana (1910 – 1913), Charles K. Akana (1915), Peter Kamano (1916 – 1920).
