Abstract

A device to control functioning of light signals with fluorescent lamps consisting essentially of an electric circuit and an electronic circuit with a connected generator of synchronization signals, the electronic circuit consisting partly of a combinatorial relay and partly of a memory unit in which the output of the electronic circuit is connected to the electrical circuit so that the output of the electronic circuit activates a control switch that causes extinguishing of all lights, the electronic circuit being capable of warning two or more consecutive malfunction signals from the lamps of the light signal. <IMAGE>
