New Yorkers trying to catch a few winks in the city that never sleeps have persuaded bureaucrats to turn down the lights.

The city began installing energy-efficient LEDs in all of its 250,000 street lamps back in February 2015 — but now it’s replacing some of those lights again because residents are complaining that they’re way too bright.

“Once again, the citizens know best. They were too bright in many cases, initially,” Mayor de Blasio said on WNYC radio Friday.

He said the city Department of Transportation has been “toning those lights down in many parts of the city.”

Around 150 complaints rolled in as soon as the installations began last year as part of a $75 million switch to LEDs that will be complete by the end of 2017.

The DOT had installed roughly a tenth of the lights with 78-watt bulbs before the growing number of unhappy residents became a glaring problem.

The rest of the street lights have or will be replaced with lower-intensity 64-watt bulbs.

Unlike their predecessors, the new bulbs reduce light pollution by preventing the glare from going “above the horizon,” officials said.

But some New Yorkers are still fired up about the first round of about 29,000 78-watt lights, which, residents say, have made some neighborhoods look like strip-mall parking lots.

The lights give the “streets an eerie day-for-night glow, like a Walmart parking lot or a zombie picnic,” Brooklyn resident Sarah Ferguson wrote in an online petition against the fixtures.

More than 500 people signed the petition, on Change.org, and many are still lighting up the Internet with angry comments.

“I can’t sleep anymore!! Light is shining directly into my bedroom!!” Michelle Casalo, of Flushing, Queens, wrote three weeks ago.

De Blasio promised on Friday to send out DOT workers to address individual 311 complaints.

“We will send out a crew, and if we think it needs an adjustment, you know, to make it less intense, we’ll make that adjustment,” he said, meaning the workers will swap a 78-watt bulb for a 64-watt one.

But the added cost will likely dim the savings the project was supposed to generate.

Before factoring in the cost of responding to the complaints, the city estimated the switch from sodium-vapor lights to LEDs would save $6 million on energy costs and $8 million on maintenance each year.

Mike Martino, a lighting specialist at The Lighting Group NYC in Midtown, said fixing a street lamp is not cheap.

“That could easily be a day’s work. You need someone on a ladder up top, a union worker,” he said. “It’s a lot more than just going up there and flipping a switch.”
