A display module which controls a sequence of lights, for interconnection with other modules of the same kind to form a display system. The module controls the intensity of each light in its sequence so as to display a time varying brightness pattern that moves at a selected rate along the sequence. The light pattern may be selected from multiple patterns generated by the module. The display module includes a parallel output for driving other modules so as to synchronously display the same pattern. There is also a serial output, whereby the light pattern, after moving through the sequence of lights associated with the display module, moves through a sequence of lights associated with another module.
