It is something that we have decided not to do as a company. while complexity and increased service calls are part of that decision, The real reason is two fold- traffic and flashes. while when we do a traditional install, we put a sign up, it looks good, it drives business. but the flashing of song driven rythym, and the traffic that comes with onlookers, drives the neighors nuts. I would not put a sign up. while many like the effect, and come to see it, the neighbors would not only not hire me, they would tell their friends not to.
however, I love the youtube videos and seeing the lights in person myself.
