It was first lighted on March 23, 1891, replacing the Old Point Loma Lighthouse which is atop the 400 feet (120 m) cliffs of Point Loma; the old lighthouse was often obscured by fog. The new light is only 88 feet (27 m) above the water. The first lighthouse keeper was Robert Decatur Israel, who had been keeper at the old lighthouse for 18 years.[4]
The original light was 600,000 candlepower and could be seen at a distance of approximately 15 nautical miles. There was also a two-tone diaphone fog horn and living quarters for several families.[1]
The light was automated in 1973.[1] In February 2013, the light that had been in use since 1999 was replaced with a VLB-44. The LED apparatus reduces the maintenance cost of the lighthouse and is brighter than the previous light.[5]
