An automatic electronic flash device or computer flash device for cameras. The device includes besides an electronic flash lamp a capacitor capable of being discharged through the flash lamp. Also there is a light sensitive sensor and a device for extinguishing the flash lamp in response to the light falling upon the sensor. There are also provided two signal lamps, one for indicating whether the capacitor is charged, and the other one for indicating that the flash lamp has been discharged. A housing which can be separated from the flash device contains the sensor. The housing is capable of being secured to a camera and both signal lamps are visibly arranged at the rear surface of the sensor housing.
