ABSTRACT:
Disclosed is a lighting apparatus for a vehicular discharge lamp which prevents the occurrence of an electric shock when the status of a vehicle is changed while the discharge lamp is on, such as when the hood of the vehicle is opened for inspection or repair. A hood open/close detector detects that the hood is opened while the discharge lamp is lit, and upon reception of a detection signal from the detector, the power supply/cutoff circuit opens a cutoff switch means to stop power supply from a battery to a lighting circuit, turning off the discharge lamp. In this manner, a person who opens a hood for work can be kept out of danger of a high voltage that is supplied to the discharge lamp.
