Royal Oak — Twinkling, flashing, gleaming and dancing — the Detroit Zoo’s annual Wild Lights attraction features a dizzying array of lighting displays of all sorts, but it’s a huge undertaking.

The zoo’s staff brings the magic to life with luminous, larger-than-life animals, an interactive talking tree and everything in between.

It’s a bit like decorating one’s own home for Christmas, said Detroit Zoo Senior Director of Guest Experience Emily O’Hara — just on a massive scale, as the zoo provided behind-the-scene access this week to their winter wonderland.

“We started counting all the lights at one point,” O’Hara said, “but you get over a million, then over 2 million and where does it stop? So, we just say millions of lights.”

This year’s display includes 676 trees wrapped with lights; more than 500 lighted “sculptures” of plants, animals and other objects; and holiday-specific items such as heating stations and a warming lodge. They all had to be set up by Wild Lights’ opening night, which this year was Nov. 23.

While the team must work swiftly, they must also work carefully. If there are too many lights on one side of a tree, for instance, they will be instructed to remove them and start over.

“There is a meticulous nature to it,” O’Hara said. “It isn’t just throwing lights and hoping they stick. We want everything to be the best product we can put out there for the guests.”

The months of hard work were evident to Phil and Carolyn Durst of West Branch, who were in Metro Detroit visiting family on Friday when they decided to check out the lights.

“We had no idea what to expect, but this is really amazing,” Phil said. “They did a great job.”

“They thought of everything, every animal you could think of,” Carolyn added.

Wild Lights continues at the zoo through Jan. 5. After that, the staff will begin tearing down the displays — carefully, so as not to tangle the thousands of strands.

Virtually all of the lights and holiday items are removed once the season is over, although some, like the large globe that can display video images, are often repositioned and repurposed for other zoo events throughout the year.

Where do the rest go during the offseason? Many are housed in the sizable storage area near the middle of the zoo, which includes eight shipping containers and a large shed. O’Hara said another 12 off-site shipping containers are used. And more lights yet get stuffed into any closets that might be available elsewhere at the zoo.

O’Hara said the staff works year-round to ensure visitors get a new experience each year. With Wild Lights entertaining families for more than a decade now, that means planning begins in January.

The staff works throughout the year to repair and repurpose aging items while the administration orders new pieces. The trend over the past few years has been on “interactive items” like a colorful see-saw and swings that kids can play on, or the talking Christmas tree that implores passersby to make a holiday wish.

Installation usually begins in late July and actually continues right up until Wild Lights opens for the season around Thanksgiving.

Once the lights are strung and the attractions in place, the work isn’t over yet. Rain and snow will occasionally cause a strand of lights to burn out. But more common are issues caused by native wildlife, zoo officials said.

“Anyone who has tried to string up lights at their own home may have encountered how squirrels find them a delicacy,” O’Hara said with a chuckle.

When items need to be tested or programmed, they’re taken to the backstage area of the Ford Education Center’s 4D theater, not only because that’s one of the largest indoor spaces at the zoo, but with the lights off, it’s dark enough to mimic the night sky outside.

“The advantage back here is we actually have a truss we can raise and lower, so it makes it much easier to reach our stuff and work on it,” said Lauri Besler-Kroll, a member of the zoo’s utility department.

During the behind-the-scenes tour for The Detroit News, team members were testing the light curtain that will be used for the special “Zoo Year’s Eve” countdown. At 8 p.m. on Dec. 31, the curtain will display an animal-themed New Year’s countdown, giving little ones who may not make it to midnight a chance to ring in 2025.

Wild Lights has become a family tradition for the family of Mike Newton of South Lyon. The dancing sticks stood out to daughter Kaylin, 5, while the rainbow-color trees were a favorite for Abigail, 3.

“They’ve been coming since they were under 1,” said Mike. “Always a good time.”
