Long Beach Light, Harbor lighthouse in Long Beach, California, US.

Long Beach Light is a concrete rectangular tower with a flat roof supported by six columns at the entrance to Long Beach Harbor. The structure stands about 13 meters tall and was designed to guide vessels safely through the waterway regardless of weather or time of day.

Established in 1949 on San Pedro's middle breakwater, the light was fully automated from the start and was called the "robot light", a forerunner of automated West Coast lighthouses. It is controlled by the ANRAC system from the Los Angeles Harbor Light. In 1968 a second navigation light was erected atop the pilot station at the Port of Long Beach.

Nicknamed the "robot light" when it began operating in 1949, it was fully automated from the start and served as the model for later West Coast lighthouses. Its beacon is run by the ANRAC system from the Los Angeles Harbor Light, and a US Coast Guard radar scanner stands beside it at the harbor entrance channel.

The lighthouse sits directly at the harbor entrance and is visible from the waterfront promenade or from a boat. Early morning or late afternoon light works best for viewing and photography from available vantage points.
