Point Pinos Lighthouse was lit on February 1, 1855, to guide ships on the Pacific coast of California. It is the oldest continuously operating lighthouse on the West Coast of the United States and even the lens is original. Alcatraz Island Lighthouse preceded Point Pinos by eight months, but was replaced in 1909 by the expanding military prison. The Point Pinos Lighthouse is still an active United States Coast Guard aid to navigation. On-site museum exhibits and other lighthouse related functions are operated by the city of Pacific Grove, Monterey County, California. The lighthouse is surrounded by the Pacific Grove Municipal Golf Links.
The present light source, located 89 feet above sea level, is a 1 kilowatt bulb, which produces a 50,000 candela beam visible under favorable conditions up to 15 nautical miles; 27 kilometres distant. Formerly, the light had a rigid schedule of being lit one hour prior to sunset, and extinguished one hour after sunrise. With automation completed in 1975, a small battery-operated back-up strobe light was installed outside the tower, and the main light was turned on permanently. The present signal has a simple 4-second cycle signature of on/3-seconds, and off/1-second. As a further navigational aid, a Class D radio beacon operated continuously which had a range of up to 20 miles . A foghorn was also located below the lighthouse closer to shore which could be turned on manually by the Coast Guard personnel when lack of visibility warranted its use. With the advent of global positioning satellite navigation in 1993, the radio beacon and foghorn were deactivated.
