Koskela Light (Finnish: Koskelan loisto) is a sector light tower located on the southern shore of Letonniemi promontory in Taskila district of the City of Oulu in Finland.

[1] The current tower was built in 1939 to guide vessels towards the Toppila harbour.

The light displayed a flash every three seconds, green, red or white depending on direction.

The focal plane was 5.7 metres (19 ft) and the range was 6.6 nautical miles (12.2 km; 7.6 mi).

[4] Due to the glacial rebound the tower is located 150 yards (140 m) away from the coastline, and is almost completely hidden by the shrub.
