Abstract

A system and method for generating and broadcasting emergency lighting signals wherein the lights are synchronized such that when a first light is energized with a packet of short, rapid bursts, a second light begins to flash before the first light is de-energized. Control circuitry connected to the power source selectively controls the packetized energization of the light sources and includes timing circuitry for periodically energizing a first of the light sources for a first duration and for energizing a second of the light source for a second duration. The second duration overlaps, but is not coincident with the first duration in a repeating pattern such that the first and second sources are periodically energized simultaneously before the first source is de-energized.
