    Abstract: The present invention generally relates to an emergency lighting system which engages when a power outage occurs. The system includes a main unit which operates via AC or DC and is plugged into a wall outlet. When power is lost, the main unit is triggered and sends an RFID signal to at least one lighting fixture. The lighting fixture may be battery operated LED equipped. The battery operated lighting fixture activates the emergency lighting source when the RFID signal is received. The main unit may send the RFID signal to numerous lighting fixtures. The lighting fixtures may receive the RFID signal even if the lighting fixture is not in the direct line of sight of the main unit.
