Douglas Head Lighthouse, Maritime navigation lighthouse in Douglas, Isle of Man.

Douglas Head Lighthouse is a white tower 20 metres tall, its base standing at 12 metres above sea level on Douglas Head, about 2 km from Douglas. The total elevation of the light reaches 32 metres. Inside, a staircase of 71 steps leads to a lantern holding eight pure silver reflectors made in 1831.

The lighthouse was established in 1857 by the engineering brothers David and Thomas Stevenson, after efforts to build a light marking the harbour entrance began in 1855. Structural problems required rebuilding in 1892, and the light was automated in 1986. It was the only lighthouse between Point of Ayre and the Calf of Man light of 1818.

The name Douglas comes from the Manx words dubh (black) and glais (stream), meaning "black stream"; some Manx people link it to the Dhoo and Glass rivers of the Greu. The tower's lantern holds eight pure silver reflectors made in 1831, still part of the light that flashes white every ten seconds.

The lighthouse sits on an open coastline with clear views of the sea, making it easy for visitors to locate. The best access is via the coastal paths from Douglas, which are well marked.

The lantern holds eight pure silver reflectors made in 1831, older than the tower itself. The optic is a 12-metre unit with two double-banked sets of twelve lamps turned by an AGA PRB21 gearless drive at three revolutions per minute, giving a white flash every ten seconds. Only eight lamps per face run normally, at 25 volts instead of 30 to lengthen their life; four 6-volt emergency lamps on each face take over if power fails.
