ABSTRACT:
An op-amp flasher for trucks, busses, ambulances and other equipment requiring flashing high power light sources. The flashing is made more noticeable and lamp life increased by increasing the spacing between the flashes so that the flashes are on less than half of the time. In a preferred form, the flashes are on a third of the time and intervals between flashes are two-thirds of the time.
