How is this done? With lots of planning, time, and maybe some late night hair pulling as well. Hundreds and hundreds of hours have been spent planning, assembling, building, wiring, and sequencing!
What You See...
In the past, we primarily used plain ol' 120-volt light strings of between 25 and 100 bulbs with preset colours that were set to be on, dimmed, or off. In 2016, a major re-do using low-voltage pixels was undertaken. Pixels are individually controllable bulbs where their colour and brightness can be set for each.
The items around the yard were made mostly from scratch with stuff that you can buy at a hardware store along with a mix of a few pre-made items that were modified to be part of our display. Our zigzag trees were entirely custom-built. The wireframe star over our living room window was bought, but it still took over 20 hours (and about 600 zip ties) to measure, plan, cut, splice, and mount all the lights on it! All of our 3D coroplast stars needed to be prototyped and built painstakingly by hand since pre-made ones couldn't be sourced anywhere. Our "regular" store-bought mini spiral trees were taken apart and "re-engineered" to use pixels; each took well over an hour's worth of work to make them what they are today.

What You Don't See...
Our light controllers and floodlights were bought from www.falconchristmas.com and www.diylightanimation.com either in kits or pre-assembled. The light display's "brains" are on a small and inexpensive BeagleBone Black computer running Falcon Player Software. Data signal cables run from the computer to around the yard to "talk" to the other light controllers.
What takes a huge portion of time is the process of sequencing the lights to the music. The computer doesn't make up random patterns on-the-fly—rather, a person needs to decide the effects to be used where and when. The xLights sequencing software offers many effects that that can be mixed together to make a show—similar how ingredients are mixed to make a cake. It can be a tedious process taking well over ten hours to sequence a song, but hobbies are all about taking up lots of free time, right? ;-)
Almost forgot: to get the music into your vehicle, we use a small FM transmitter that's plugged into the computer's audio output. It's designed to transmit only a few hundred feet since there is no need to have it go any farther than you can see the display.
