The invention relates to a circuit arrangement for revealing light signal errors, in particular for railway safety systems, comprising an electronic signal generator (1) which can be disconnected in a reversible manner in the event of an error, and a control part which is designed for incandescent lamps for controlling and monitoring the signal generator (1). Said device for revealing errors comprises an error differentiator between the line-related interference voltage and error of the signal generator (1). According to the invention, in order to improve the reliability of the error differentiator and independently from the capacitive intermediate energy store, said signal generator (1) is connected to a resistance arrangement such that the signal generator voltage is greater, in high-resistance signal generators (1), than the interference voltage.
