Abstract: An electronic circuit comprised of several integrated circuits sequentially actuates a plurality of light-emitting diodes (LED's) located in an article such as eyeglass frames, which are carried or worn by a person. In one embodiment, an oscillator driven binary up-down counter drives first and second binary to one-of-four decoders. The LED's are arranged in an electrical circuit which allows them to be addressed in X-Y matrix fashion. The first decoder sequentially addresses each "row" of LED's while the second decoder sequentially addresses each "column" of LED's in the matrix so that each LED in the matrix circuit is sequentially flashed. After the entire array of LED's has been sequentially actuated a predetermined number of times, the up-down counter is electronically switched to the opposite state so as to reverse the order in which the LED's are sequentially actuated. In a second embodiment, an integrated circuit binary ripple counter/oscillator drives first and second demultiplexers.
