A new leading light for the Elbe.

The leading light line between the old Mielstack front light and the Somfletherwisch rear light marks out the shipping channel through a curve of the Elbe river for vessels navigating up-river near the mouth of the Lühe at Stade.

The new Somfletherwisch front light tower has been built on a deep reinforced concrete foundation. The shaft of the tower is a steel construction with a diameter of approx. 3 metres. The lantern has been newly built in the style of historic models.

For the nautically-minded: The leading light has a visibility of 12.3 nautical miles and marks out the 136° course line. The call sign of the front light is "Iso 8s". This means that the light illuminates in regular phases of 8 seconds: 4 seconds on, 4 seconds off ...
