For signal luminaires which indicate the term STOP or DANGER upon activation, a circuit containing a first operating case feed unit and a second auxiliary source is provided for the purpose of supplying a reliable power supply. In this case, the second auxiliary source is inductively coupled to the signal luminaire electric circuit; while the signal luminaires are capacitively coupled to ground. The use of switches during operation in a fall-back level is obviated in this way.
