ABSTRACT:
A load drive (1) having a pulse converter (2) and a DC/DC converter (5). The pulse converter (2) is capable of converting a high DC voltage supplied from the power supply unit (10) of a vehicle to a pulse voltage and applies the pulse voltage to a first lamp (L1). The DC/DC converter (5) operates to convert the high DC voltage to a low DC voltage whose voltage value is lower than the voltage value of the high DC voltage and applies the low DC voltage to a second lamp (L2).
