A flash beacon is described which uses a strong bright initial flash to attract attention followed by a series of weaker flashes to enable a person to easily locate the beacon source. The weaker flashes may be broken into code groups for identification or other purposes. An electrical circuit utilizing three capacitor banks interacting with each other, is described for operating the flash sequences.
