Abstract
Flashing lights powered by a common wild frequency power source () are synchronized with respect to flash rate and duration. Each lighthead includes a power supply device (), which includes a timing signal generator () and a synchronization device (). The timing signal generator () includes a precision clock (), which generates a timing signal to regulate the flashing operation of the corresponding light. The synchronization device recurrently causes the timing signal to be reset in accordance with the wild frequency power source signal. By recurrently resetting the timing signal of each light according to a common wild frequency source, the flashing of the lights can be synchronized without transferring synchronization signals between the lights.
