Our LauderdaleChristmas.com 47,000 LED holiday lights display with 112 channels from 7 computerized lighting controllers. I act as orchestrater, tell the lights when to turn on or off, fade, twinkle, etc. An MP3 player inside the controller plays the music and controls the lights according to your programmed orchestration. We transmit it to people's cars radio via low power transmitter on unused 100.9 FM.
