ABSTRACT:
An operation indicator for auto-strobo unit which includes a single light emitting element capable of indicating the completion of a charging operation or a flashlight illumination of the auto-strobo unit, comprises a bypass circuit which any current flow associated with the indication of the completion of a charging operation is bypassed whenever a current flow associated with the indication of the completion of a flashlight illumination is produced, thus allowing the indication of the completion of a flashlight illumination to predominate over the indication of the completion of a charging operation.
