Title: Warning light control

Abstract: The visibility of warning lights employing flash tubes is enhanced by control circuitry which generates closely spaced trigger pulse pairs for energizing the tubes to thereby produce double flashes. Noticeability of the warning light may be enhanced by addition thereto of a noise maker which operates off the same power supply that provides a high voltage for operating the flash tube or tubes.
