The light was established in a granite tower in 1858.[4] It was automated in 1923, deactivated five years later and demolished in 1952.[5][6] It was replaced with a white 30-foot pyramidal day beacon.[7][8] The day beacon was replaced with a round, orange and white 30-foot tower placed on top of the original Bishop & Clerk's granite base in 1998.[9][1][10]
