ABSTRACT OF THE INVENTION The invention provides a light source for use with diagnostic devices such as laparoscopes having a male fitting to receive a light tube connection for transmitting light within the device to an end for viewing using an eyepiece on the device. The light source has an elongate casing and an electrical storage battery contained in the casing. The battery extends longitudinally and has first and second poles at opposite ends of the battery. A tubular insulating insert is positioned inside the casing at one of the ends of the casing and adjacent the first of the poles. A bulb is located in the insert and has the center terminal of the bulb in electrical connection with the first pole. First and second contacts are insulated from one another and located by the insert with the first contact coupled to the body of the bulb and the second contact coupled to the second pole. Both the contacts project slightly inwardly within the insert whereby when the light source is pushed over the male fitting, the light source is located on the diagnostic device and the male fitting completes the electrical circuit. The bulb is then powered so that light passes through the device to the end of the device.
