ABSTRACT:
A motor vehicle headlamp in which electromagnetic waves generated when the discharge bulb employed therein as the light source is activated are prevented from leaking out of the headlamp and interfering with other circuitry on the vehicle. The lamp body of the headlamp is made of a conductive material, or an insulating resin coated with a conductive layer. The lamp body or conductive layer is grounded to the body of the vehicle, thereby to ground out potentially interfering electromagnetic waves generated inside the lamp body.
