Today Lückenburg is part of the Verbandsgemeinde of Thalfang am Erbeskopf.

The council is made up of 6 council members, who were elected by majority vote at the municipal election held on 7 June 2009, and the honorary mayor as chairman.

[3] The German blazon reads: Schild von eingebogener grüner Spitze, darin ein silberner Turm, rechts und links von je zwei silbernen Eichenblättern begleitet, gespalten; vorn in Silber ein rotes Balkenkreuz, hinten in Gold ein blaubewehrter roter Löwe.

The municipality's arms might in English heraldic language be described thus: Tierced in mantle, dexter argent a cross gules, sinister Or a lion rampant of the second armed azure, in base vert a tower of the first between four oakleaves palewise of the same, those in dexter in bend and those in sinister in bend sinister.

The cross on the dexter (armsbearer's right, viewer's left) side is from Electoral Trier's old arms, and the lion rampant on the sinister (armsbearer's left, viewer's right) side from those borne by the Waldgraves and Rhinegraves.
