摘要：Each discharge lamp (5) housed with a reflector (4) in an external housing (2) is supplied with AC from a circuit (6) incorporating an autotransformer (17) with a tap (18) giving a very high transformation ratio (N2:N1) normally greater than 100. A capacitor (19) of high dielectric strength is connected across the smaller part (N1) of the autotransformer winding and charged from the inverter (7) through a PTC resistor (21). Other lamps (5') in separate housings are driven by identical circuits (6') fed from the same inverter (7) and battery (9). ADVANTAGE - Need for separate ignition circuit and inverter for each headlamp is eliminated.
