"Due to increased electricity costs, and the time it takes to put the display up, we made the decision that this, our 35th year, would be the last," a note on the home's gate said, the Detroit News reported.
Ethlyn Unger, who has decorated her Royal Oak home with her husband, said it was the visitors' letters that kept them going.
"I keep all the letters, and one was from a woman who said she comes from an hour away, and she'll be here before it's over just for one last look," Unger said. "Another woman wrote to us saying she had fallen on hard times, and when she came out to see the lights, it cheered her up."
The display features Santa singing "We wish you a merry Christmas" near the home's entrance, as well as angels, nutcrackers, a reindeer parking meter and a towering Christmas trees, the News reported.
There's also a digital timer on the porch counting down the days to Christmas.
Most of the decorations will be split up between their eight children, Unger said.
