Abstract
A warning light system constructed of an array of flashable, warning lights. The warning lights are self-contained, battery powered warning lights that may be arranged in an array and controlled to flash simultaneously. Each light includes an individual transceiving system for transmitting a coded, radio frequency signal to each other light of an array and a receiving radio frequency signal from each other light of the array to cause each lamp of each light to flash on and off in synchronism. Each light has a built-in transceiving antenna arranged within the light lens assembly and completely housed therein.
