From the YouTube description:
Over 16K lights and many thousands of channels of computer animation. This is a personal hobby and not a business. Edwards Landing Lights is simply the name we gave to our holiday display on our house. Viewers tune in their car's FM radio to "hear the lights". No music is broadcast outside. Most of the lights used in the display are energy efficient LEDs. We estimate the electric bill for the display is $25-$35 to run the display for the Halloween season.
