The Famous Light Bulb Brain Teaser Is Seriously Puzzling – See If You’re Bright Enough To Solve It

From time to time we like to share a really tough riddle with all of you, and this one captured our attention recently.

It managed to divide everyone in our office as we argued over how to solve it, but we promise there is an answer, and it can be solved.

See if you have the mind to un-puzzle this one, then share it with a friend to challenge them.

Here’s the brain teaser:

“Mr. Bright was doing some renovations on his home when he ran into an unusual problem.

Like a lot of renovation problems, it involved his home’s faulty wiring.

In Mr. Bright’s basement, there was a set of light switches.

A note from the home’s former owner explains that the three light switches are connected to three different light bulbs in the house’s attic.

Mr. Bright can’t see which light bulb turns on in the attic when he flips a switch in the basement.

While each switch is connected to just one light bulb, all three light bulbs and switches look exactly the same.

Because Mr. Bright is getting older, he doesn’t want to walk back up and down his stairs. He will flip as many switches as he needs to, then walk upstairs just once to identify how the switches and light bulbs are connected.

To be clear, there’s no way to turn the lights on or off once Mr. Bright walks out of the basement to check on them.

And no, Mr. Bright can’t use a dimmer switch, or ask someone else to help him.

So here’s the puzzle: how can Mr. Bright identify all three switches and lights in just one trip from the basement to the attic?

Small Town Catches Grinchy Squirrel Wrecking Their Christmas Lights

There are less than 2,000 people in the small town of Sea Girt, New Jersey, and last week all of them became suspects in a bizarre vandalism case.

City workers were testing the town’s Christmas tree before the lighting ceremony on Friday, when they realized the lights weren’t working at all. A closer investigation revealed the wires had been “sliced and cut.”

Soon, the townspeople were on the hunt for a Christmas vandal, and news reports blamed naughty kids for the damage. “Somebody is trying to steal the spirit of Christmas,” one local complained.

City workers were forced to scramble to keep the lights working until the ceremony, and to watch the tree carefully in case the Scrooge who wrecked it came back.

Meanwhile, the police were baffled by the crime, and hoped that news coverage would help them identify the holiday display vandal. In the end, they were right: someone had wrecked the display, and they were caught thanks to the extra attention.

But nothing else about this case turned out the way police imagined.

Town Full Of Grinches Try To Shut Down Family’s Elaborate Light Display

For almost 20 years, the Halliwell family of Fairfield, Connecticut have lit up their town with a special Christmas tradition.

Beginning the night after Thanksgiving, the Halliwell family home transforms into “Wonderland at Roseville,” a holiday display that attracts thousands of visitors each year. The Halliwells deck their halls with more than 300,000 lights, a model train, life-size Christmas figures and other decorations. They also play Christmas music to set the mood.

There’s a small fee to admire the sound and light show, and all the proceeds are donated to a local Shriners Hospital. It’s hard to imagine a more wholesome way to celebrate the holiday season, but Wonderland’s neighbors are saying “bah, humbug” to this year’s display.

A petition signed by 45 neighbors from 28 nearby households says that the wonderland display puts children and the elderly in danger. The Halliwell family’s neighbors complain that the surge of cars on their street around Christmas is a risk and a nuisance.


“During the time that Wonderland at Roseville operates, the constant noise, the flow of people walking in the streets and many walking across our lawns, and the litter left behind are all a serious nuisance to our residents,” the petition reads.

The Halliwells say they’re “not happy” about the complaint, and are telling their side of the story.
