ABSTRACT:
A sequential light flashing circuit usable as a decorative display for Christmas decorations or the like includes a switching circuit for energizing lights in a predetermined sequence to provide a variety of distinct light patterns. A thyristor brightness control circuit is employed in conjunction with the sequential switching circuit to vary the brightness of each light during its operating interval. The operation of the sequential switching circuit may be stopped at any desired point to permit any light pattern in the sequence to be continuously displayed.
