The part of Germany west of the Rhine river was occupied by French Revolution troops in 1792, and in 1795, the French dissolved the old borders and created new administrative districts, placing Lichtenberg Castle in the Saar Department.

In 1945 the district of Birkenfeld, in which Lichtenberg Castle lay, became a part of the new state of Rhineland-Palatinate.

In 1971 the castle was handed over by Rhineland-Palatinate to the district of Kusel, and restoration work began.

Some of the restorations include the reconstruction of the tithe barn and the repair and roofing of the bergfried.

From the bergfried, one can see the Remigiusberg monastery church and ruins of the nearby Michelsburg castle, as well as the Potzberg hill.
