FIELD: railway transport.
SUBSTANCE: invention relates to control or warning devices installed along route of trains or locomotives. Proposed device contains two light-emitting diode circuits connected to ac voltage source through capacitor and contact of signal relay. Light-emitting diode circuits are antiparallel connected. Jumpers are provided between junction points of light-emitting diode circuits.
EFFECT: reduced cost of capacitor-type light-emitting diode light signal owing to dispensing with diode bridge circuit.
