Before the tower was turned into a lighthouse in 1814, the dangerous reef and sandbank of Scharhörn was marked by multiple beacons and bearing aids, most importantly the Scharhörnbake.
The most important was the bearing of wooden beacons north-west end of Neuwerk and its tower to find the smaller beacon in the open sea.
Today's "Nord-Bake" still shows the form of a beacon to overshadow an open fire once the ships reached this bearing.

The Carta Marina shows a fire beacon on "Nuge uirk" as early as 1539, but other sources mention the open coal fire beacon not until 1644: It was a navigational aid during night time.
This required 1000 tons of imported Scottish coal a year starting from 1761.
This coal contained more bitumen and burned much brighter than the usual German hard coal.

The tower was only turned into a lighthouse on December 20, 1814.
The first lamp was made of 21 hollow wick oil lamps with parabolic reflectors and burned on colza oil and kerosene starting 1870.
A fresnel lens of measuring a focal length of 700 mm was installed 1892 together with a five-wick kerosene lamp, to improve the brightness even further.
This lens is still used today.
The lamp was again improved in 1908, to be first electrified in 1942.
Electricity was needed to shut down the light quickly during World War II.
The kerosene lamp were kept in place as there was no emergency power supply and upgraded to propane in 1949.
The luminous intensity was stated in 1952 to be 5700 Hefner lamps (HK) 13200 seaside, 1000 for the green and 550 for the red light.
The reach of the 1000 watt lamp was roughly 30 kilometers.
Is could be seen from Heligoland und good conditions.
The classic electric lamp was replaced by a Halogen lamp in fall 2007.
On February 10, 2014 it was replaced by LED.

Although belonging to Hamburg, the lighthouse was operated by the Wasser- und Schifffahrtsamt Cuxhaven, which is responsible for the Elbe estuary.
As the lighthouse was non-essential for shipping it was decommissioned on January 1, 2014 and turned over to the Hamburg Port Authority.
On February 10, 2014 it was officially shut down after almost 200 years in operation and continues as a "private light" under the authority of Hamburg.
The original light characteristic "Blk.
 (3) w. r. gn.
 20 s 16–11 sm" was switched to a steady white lamp with a reach of barely 3 nautical miles.

The original open coal beacon was replaced by the small lighthouse after the great lighthouse started operating and functioned together with him as leading lights.
This allowed for safe passage from north-west over the Vogelsandsteert.
The forementioned open fire beacon, the great and small lighthouses and today's "Nord-Bake" all were established on the same bearing.
The small lighthouse was torn down in 1909.
