A MULTIVIBRATOR CIRCUIT COMPRISING TWO LIGHT SOURCES VARIABLE IN RESPONSE TO AN ELECTRICA SIGNAL APPLIED THERETO, A FIRST PHOTORESPONSIVE IMPEDANCE ELEMENT CONNECTED IN ELECTRICAL APARALLEL RELATION TO A FIRST OF SAID LIGHT SOURCES AND LUMINANE COUPLED TO THE SECOND OF SAID LIGHT SOURCES, A SECOND PHOTORESPONSIVE IMPEDANCE ELEMENT CONNECTED IN ELECTRICAL PARALLEL RELATION TO THE SECOND LIGHT SOURCE AND LUMINANCE COUPLED TO THE FIRST LIGHT SOUCE, MEANS FOR APPLYING AN ELECTRICAL ENERGIZING SIGNAL ACROSS BOTH SAID LIGHT SOURCES, SAID CIRCUIT HAVING AN ASYMMETRY WHEREBY ONE LIGHT SOURCE BECOMES LUMINANT AND THE OTHER IS NON-LUMINANT IN RESPONSE TO THE APPLICATION OF SAID SIGNAL, AND MEANS FOR CAUSING SAID LUMINANT LIGHT SOURCE TO BECOME NON-LUMINATN AND SAID NON-LUMINANT LIGHT SOURCE TO BECOME LUMINANT COMPRISING SIGNAL INPUT MEANS CONNECTED TO APPLY AN INPUT SIGNAL SIMULTANEOUSLY TO EACH OF SAID LIGHT SOURCES THROUGHT ITS RESPECTIVE ELECTRICALLY CONNECTED IMPEDANCE, EACH SAID LIGHT SOURCE BEING IN ELECTRICAL SERIES RELATIONSHIP WITH ITS SAID RESPECTIVE ELECTRICALLY CONNECTED IMPEDANCE RELATIVE TO SAID SIGNAL INPUT MEANS.
