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.
