The lighthouse was put into operation in 1904.
A small metal tower with three glass panes, inside which an oil burner burned with an open flame. The lamp housing was made of brass and diffusers were made of
clear glass. The lighthouse included a copper kerosene tank with sufficient contents for seven days.
Initially, the lighthouse was probably operated by Captain Konrad Jakobsen, who lived nearby.
Since an accident at sea, he had a wooden leg and could only walk with crutches.
The work consisted of carrying and refilling kerosene, replacing the wick, and cleaning lamp glasses and window panes. The Brøtt lighthouse was in operation from approximately August 1 to approximately May 30.
Over time, all the lighthouses were electrified. At the end of the 1970s, a new lighthouse was put into operation at the bridge over the Saltstraumen Lake. The old lighthouse had served its purpose.
