Robert and Lori Osenkowski’s spectacular holiday light display has been well-known in their hometown of Bristol for years. Now the whole country knows about it, after the elaborate color-changing spectacle won a “Deck the Homes” holiday contest on TV’s “Live with Kelly and Ryan.”

“We entered just before the deadline,” Lori Osenkowski says. “We knew nothing about it,” her husband says, until their neighbor Lynn Gaski happened to watch “Live with Kelly and Ryan” on a day off from work and urged them to enter the competition. “So I put the drone in the air, took a few minutes of video and sent it in. We didn’t take it seriously.”

The Osenkowskis won a week’s vacation in Hawaii worth an estimated $8,500. Rob and Lori say it will be the first big get-away they’ve had since their honeymoon in the Bahamas in 2008.

The “Deck the Homes” contest highlighted the top contestants over several days of “Live with Kelly and Ryan.” The winner was revealed on Wednesday’s special episode “Live with Kelly and Ryan: A Very New York Christmas!”

The winning house was decided by national online voting, and the Osenkowskis say they are humbled by how many of their fellow Bristol residents told them that they had voted for the house, and by the nearly 2,000 “likes” that the display has received on Facebook.

The Osenowskis have lit up their house, known locally as “Lights on Rosewood,” for the last nine years. Comprising 15,000 LED lights, display changes in time to music that is broadcast over a low-frequency radio channel.

The display changes somewhat every year, as does the music selection. “Every year there are new songs, new elements,” Robert Osenkowski says. “The songs are old school, new school, what our kids are listening to.” New on the soundtrack this year: Kelly Clarkson’s “Christmas Isn’t Canceled (Just You).”

Besides the entertainment value and illuminating holiday spirit, Lights on Rosewood has been used since the beginning to raise money for those in need in the Bristol area. Every year a different beneficiary is chosen. This year it is Carrie Barganier, a respiratory therapist and mother of three young children in Bristol whose husband Nate died in June.

All the money that is donated to Lights on Rosewood goes to that year’s beneficiary. Besides on-site donations, the Osenkowskis also collect canned goods to donate to a Bristol-based outreach organization for the homeless, Brian’s Angels.

Inspired by the Osenkowskis, Dustin Alley, the pastor of Liberty Baptist church in Bristol, took up a separate collection for Barganier, for which a parishioner offered to match all the other church members’ donations. Around $3,500 was raised through Liberty Baptist alone.

Another donation, of $500, came from the 2016 recipient of the charity, the Albert family, who lost their son Connor and have since founded a nonprofit in his name, the Captain Connor Albert Foundation.

The Osenkowskis have three children, ages 8, 11 and 12. “They love to see the lights and be part of the whole experience,” Lori Osenkowski says. “It’s great for them to see people show up, wanting to give to others.”

The Osenkowskis nearly stopped doing the displays a few years ago, following complaints about traffic and other disruptions in the neighborhood. The lights-and-music show was shortened from an hour to 20 minutes and put on a tighter schedule, which Robert Osenkowski says has improved the display overall while also satisfying the neighbors.

It takes about a month to put up the lights each year. “Every year I get a little better at it,” Robert Osenkowski says, “and it takes a little less time.” Some of the lights are strung on mesh screens that cover the house’s windows. The lights are RGB smart pixels, programmed though a controller so they can be blended into “any color in the rainbow,” Robert Osenkowski says.
