Abstract
A system and method for automatically supplying a flashing line voltage from power stored in an auxiliary battery to power red traffic signal lamps using clusters of light emitting diodes during a blackout condition. A plurality of flash block connectors are pin-to-pin compatible with the flash block jumper blocks of an already installed traffic light control system so that the existing system is retrofitted without any cabinet or field rewiring or any cutting or crimping of the wires.
