At the time, the illuminating equipment had not been selected, as the lighthouse was designed to be fully automated and controlled from facilities at La Créac'h.

Due to the violent currents and reefs in the Iroise Sea, site access was difficult, and the construction process was extremely dangerous.

A concrete belt strengthening the base of the lighthouse was added due to fears expressed by engineer Cône.

The illuminating equipment was selected on March 19, 1928 by the supervising ministry, which proposed the construction of first three, then finally two concrete pylons, an overhead power line and a small cable car.

The gas emergency light was operational from October 1931, and the station was tested beginning in the early summer of 1933, before being commissioned in 1936.

For strategic reasons, the German command decided to extinguish all the lighthouses on the coast, including Nividic.

In 1943, after 3 years of abandonment, the cable system succumbed to corrosion, rendering access to the lighthouse impossible by land.

While the cable car system was never rebuilt, attempts were made to return the light to service using the gas-powered emergency beacon.

Following advancements in technology, in 1958 a temporary wooden helipad, 5 meters square, was built atop the lantern room.
