Keelung Lighthouse is located at Wanrendueibi, a cape protruding to the sea near the Keelung Harbor. Starting from 1899, the construction of the lighthouse was completed in 1900. This brick and tubular building was installed with the kerosene lamp shining white and red fixed light. The lighthouse was refitted with the acetylene lamp in 1913, then re-equipped with the alternating current (AC) lamp that shone red and white occulting lights every six seconds in 1932. Later on, the lighthouse was re-equipped with electric flash lamp that flashed red and white beams of 7,500 candlepower twice consecutively every seven seconds in 1956. In 1969, the lighthouse was refitted with the fourth-class electric lamp that generated higher power of 21,000-candlepower white light and 3,600-candlepower red light. Since May 16, 1989, the red beam was replaced by the white beam with the same lighting candlepower.

　　The lighthouse was originally installed with red arc-light signals to mark the position of Sinlai Reef ouside the Keelung Harbor. The hidden reef is submerged and dangerous that caused several wrecks there before. The red arc-light signals were removed after the dangerous reef was blew up in 1989.

　　The fourth-class radio beacons were set up to guide vessels in 1957.

　　The lighthouse and houses were all rebuilt with bricks and reinforced concrete in 1962. The water supply facility was built at the same time to improve the lives of lightkeepers.

　　Radio beacons was refitted into the second-class beacons in 1973. Output power was increased to 300 Watt and radio range was increased from 10 nautical miles to 100 nautical miles.

　　Radar beacons was installed in 1983.
