ABSTRACT:
An actuator circuit unit of a discharge-type headlamp is connected through a connector to a discharge bulb located within a lamp body, and is inserted and fastened to a mounting hole of the lamp body with the actuator circuit unit protruding rearward of the lamp body. A connector of an output cord from a ballast circuit unit, which is located near the headlamp, is removably inserted into a connector connection portion attached to the outer surface of the actuator circuit unit. By turning the actuator circuit unit along and within the mounting hole, the unit can be pulled out of the mounting hole. A rotation blocking member (rib), which projects rearward from the rear wall of the lamp body, is provided in the vicinity of the mounting hole. When the actuator circuit unit is turned in the removal direction, the rotation blocking member comes in contact with the connector that has been inserted into the connector connection portion, blocking further turning of the unit. The removal of the actuator circuit unit and bulb exchange are prevented until the output cord is disconnected from the actuator circuit unit and the supply of power to the actuator circuit unit is stopped.
