Mike Carter has almost doubled his love of the holidays each year since 2014.

And he shows it in a most visible — and rhythmic — way: Each night he cranks up a seasonal light and music show that has gotten bigger and brighter each year on his house at 710 11th Ave. NW.

In 2014, he constructed a light display at his home hosting 7,000 lights.

Last year, that grew to 14,000.

And this year? Well, it did not quite double, but it was still significant, at an illuminating 22,500 LED lights, plugged into 57 plugs or circuits – and that, by the way, is more than an average house.

“Well, I’ve always loved lights, my whole life,” said Carter with a chuckle. “But I have to admit, I was thinking this year, ‘I can’t keep this up; there’s no place to put any more.’”

The display is bright and busy, with singing trees and a 16-foot drummer boy.

“We [including his spouse, Freddy] built the drummer ourselves,” he said, adding they used corrugated plastic sheets to fashion the boy.

“I think it took me three hours to drill 1,400 holes” into which bulbs were fitted.

Each of the trees has 750 lights and the display uses about 500 feet of extension cords.

But the most important part of the entire expanse is the four computers he uses to run the show. He has played with computers “my entire life; so I was able to build these,” he said, which cut down the cost of the display considerably. The computers, he added, are no larger than a credit card.

And, the cost of the display was also reduced by the use of LED technology, and he gets a rebate (as does anyone using them) from the Austin Utilities. He estimated cost savings at 25 percent.

The display began in 2014, and music was added in 2015. This year’s warm fall provided ideal conditions for getting the display just the way he wanted it.

“That wasn’t true in 2014, when we had that really cold winter … I was out there, trying to put things up and I was thinking, ‘I am never doing this again.’ ”

Thankfully for children and adults alike, he changed his mind. From 5 to 9 p.m. every night, the display, is synchronized to music — he has a singing tree that even raps; visitors should tune into 93.5 FM — is lighted for viewing. The display is left on an hour later on Friday and Saturdays, and then on Christmas Eve and Christmas Day. The display Is lighted through Dec. 31.

Carter estimated about 10 cars come for each “performance,” which lasts 10 minutes before starting over again. The show began drawing visitors just after Thanksgiving and traffic has been brisk.

“The neighbors have been great about it; I haven’t heard any complaints,” he said.

Carter also keeps a donation box on the corner of the property. All proceeds are donated to a local non-profit organization. Last year, the $170 collected help to send a local Boy Scout to summer camp.
