AES Indiana window lights began in 1954 with red and green stripes for Christmas. Maintenance crews had to change each bulb by hand to get the different colors. Today, AES Indiana’s 10-story building has 267 individually controlled windows, each equipped with 36 high-efficiency bulbs that can generate 16 million different color combinations.
