1. A device for creating sequential illumination patterns in a plurality of illumination sources comprising:

  • a switching unit having first and second sets of output leads;

    first sequential energizing means for sequentially energizing each lead in said first set of output leads;

    second sequential energizing means for sequentially energizing each lead in said second set of output leads Each time one lead in said first set is energized; and

    one or more logic circuits each including an OR gate having two or more inputs and further including an enable input, each logic circuit having an output connecting to one of the illumination sources and arranged to illuminate the illumination source when the enable input and one of the OR gate inputs are simultaneously energized;

    circuit means connecting the inputs of the OR gate within each logic circuit to leads in one of said sets of output leads; and

    circuit means connecting the enable input of each logic circuit to a lead in the other of said sets of output leads.
