This used El Wire (electrolumenescent wire), which was the technology that I used prior to using LED's and fiber optics.
the cane is a clear acrylic cane that I bought on line. I then drilled holes in it to insert LED's. Unfortunately, I had weakend the cane and it broke in half shortly after I took this picture.
After two years, I had to retire this coat because the El Wires are too fragile to use in garments that are actively worn.
