FIELD: transport.
SUBSTANCE: floodlight signal comprises support, optical system with lamp, electromagnet and supported frame with light filters. This signal incorporates second optical system with lamp its optical axis being aligned with that of said first optical system and beam outgoing from reference point located at the line of labile equilibrium to pass via light filter center. Said electromagnet can interact with the frame made of magnetic material magnetised by interaction with electromagnet and accommodating light filters arranged in pairs. Centers of said light filters can be aligned with optical axes of said first and second optical systems after said frame passes by said liable equilibrium position.
EFFECT: higher reliability operating performances, and fast operation.
