ABSTRACT:
An indicator circuit for an auto-strobo unit comprises a switching element which rapidly discharges a capacitor which, when adequately charged, feeds a display element indicating proper operation of the auto-strobo unit. The switching element is turned on in synchronized relationship with the initiation of a flashlight illumination from a flash discharge tube to discharge any remaining charge on the capacitor, thus providing a reliable indication of each flashlight illumination of the flash discharge tube.
