Abstract
Abstract A DUAL INTENSITY LIGHTING CIRCUIT IN WHICH THE LOW BEAM FILAMENTS OF THE VEHICLE HEADLAMPS ARE ENERGIZED TO PRODUCE LESS LIGHT OUTPUT WHEN THE VEHICLE ENGINE IS RUNNING, AND THE LOW BEAM FILAMENTS ARE SNOT ENERGIZED THROUGH THE CONVENTIONAL HEADLIGHT LIGHTING SYSTEM, THAN WHEN THEY ARE ENERGIZED THROUGH THE CONVENTIONAL LIGHTING SYSTEM. THE OUTPUT FROM ONE OF THE OUTPUT TERMINALS OF A THREE PHASE ALTERNATING CURRENT GENERATOR IS SUPPLIED TO THE LOW BEAM FILAMENTS TO PROVIDE FOR THE DIMINISHED ILLUMINATION THROUGH A BLOCKING DIODE.
