专利汇可以提供Aircraft flasher unit专利检索，专利查询，专利分析的服务。并且Apparatus is disclosed which provides for the pulsing of a plurality of high intensity white lights, which lights are synchronized to flash simultaneously, and during the off period of navigation lights already installed on the airplane. Each high intensity light is controlled by a transistorized circuit coupled to the power supply lead which supplies the navigation light. Said circuit charges two storage capacitors and holds the charge on same during the on period of the navigation lights. During the off period of same, a short circuit is presented, causing a discharge of one of the capacitors, which acts to trigger the high intensity light, the burst of light being energized by the discharge of the other capacitor.，下面是Aircraft flasher unit专利的具体信息内容。
