Abstract
An electronic flashlight may be removably assembled to a camera. The camera is provided with a mounting member, an indicator lamp for indicating the readiness of the electronic flashlight for flashing, and contact means connected with the indicator lamp. The electronic flashlight is provided with a mounting member for engagement with the mounting member of the camera removably to secure the flashlight to the camera, and contact means. The contact means of the camera and the contact means of the flashlight may automatically be connected together upon assemblage of the flashlight to the camera electrically to connect the indicator lamp with the flashlight. The indicator lamp is located for observation through the viewfinder of the camera. When the camera indicator lamp, a glow discharge tube, is connected into the flashlight circuit by attachment of the flash unit to the camera, the flashlight indicator lamp, also a glow discharge tube, is automatically extinguished because of a resulting voltage decrease across a voltage dividing resistor.
