Annotation:
This article discusses the principle of monitoring the health of switched off traffic lights by implementing a pulsed test action, defines the parameters of the main elements of the test circuit, as well as the time parameters of the testing pulses. During the presentation of the material, the possibility of distinguishing the state of the thread of the turnedoff lamp in the conditions of extended cable lines was confirmed by calculation, and options for the practical implementation of test circuits were proposed.

Key words:
test of the cold filaments, the distinction between the states of the filament, power test exposure, test pulse impact, a generator of test signals, test pulse energy, the duration of the test pulse, the resistance of the charging circuit
