A high intensity discharge (HID) bulb fixing apparatus assembles an HID bulb securely in a reflector. The HID bulb includes a circular mounting ring. The HID bulb fixing apparatus includes a base disposed at a rear end of the reflector, and a catch base detachably assembled on the base. The base includes a basal wall, and a bearing flange projecting from an inner circumferential surface of the basal wall and for bearing the mounting ring. The catch base includes two fixing walls clamping at front and rear sides of the basal wall, and two clamping parts clamping at left and right sides of the basal wall. The fixing wall located at the rear side presses against a rear end surface of the basal wall and a surface of the mounting ring. The HID bulb fixing apparatus is applicable to fixing and mounting HID bulbs of different specifications, such that different bulbs may be mounted in reflectors of the same type.
