CRANBERRY TWP — One family has gone all out for Christmas, stringing up more than 30,000 lights that are synchronized to music that plays through your car stereo.

And, it’s all for a good cause, as any donations the family receives are given to an organization that helps children with autism and other developmental disabilities.

The free show offers residents the chance to pull up to the home at 502 Hedge Row Court, tune-in their radio and enjoy the show at their own leisure. Called the Baker Family Christmas Extravaganza of Lights and Music, the show is the culmination of more than a year’s worth of work by the family to construct the intricate display.

According to the family, the display includes tens of thousands of Christmas lights, more than 3,000 feet of extension cords and a Christmas tree that tops out at more than 21 feet tall.

The show runs daily from 5 to 11 p.m. and will continue through Jan. 4.

For the Bakers, the show takes countless hours to organize and execute, all from scratch.

Wayne Baker, the technical genius behind the project, said it takes 20 to 40 hours to program the lights to a certain song. He said there are 10 songs in the show’s catalog for viewers.

But it’s a labor of love, said Baker, who is an electrical engineer in the Thorn Hill Industrial Park.

“He’s always doing a project,” said his wife, Jennifer. “He can’t sit still.”

Neither could Chris, the couple’s 11-year-old son who was diagnosed with autism several years ago.

The young boy’s face lights up brighter than the Christmas lights when he talks about the show. He’s proud of his family’s effort to brighten up the holidays, and the show certainly gives him bragging rights at the Pace School in Churchill, the same school that will receive all the donations from the show.

“It’s awesome,” he said about the show. “Especially because there are 30,000 lights.”

The show has become an attraction, especially for neighbors along Hedge Row Court.

Jennifer Baker said children on the street sit on their front porches and drink hot chocolate every night watching the show right before bed time.

And that’s not to mention all of the strangers who pull up and watch the show, which includes a lifelike imagine of Santa projected in one of the windows of the house.

Wayne Baker admitted that it takes a little bit of insanity to undertake such a project, although he urged anyone interested to contact him to learn more about the intricacies.

The family’s electric bill this time of year is only about twice as much as normal, which means the project isn’t cost-prohibitive to the family.

Sometimes there are glitches in the program, sometimes creatures like slugs get fried in the controls. But mostly the program runs as planned, spreading holiday cheer to anyone with a radio.

This is the fifth year of the show, Wayne Baker said, and the family continues to add additions to it. But that doesn’t mean the show will grow exponentially each year.

“Some people overdo it, and some people might say we already overdo it,” he said with a laugh. “But we never want to get to that point.”

The work to set up the show takes several weeks, while it is usually up and running right after Thanksgiving.

The expense and hard work are worthwhile, though, when the first car pulls up with squealing children inside. “It definitely takes a significant amount of work,” Jennifer Baker said. “But it’s all worth it.”
