Necessity Was This Invention’s Mother

Halo Life + Light could light way to safety, Brown says

Two teenage girls are coming home at night. They walk through a dark gangway to reach the house’s back door.

But a bulb is missing in a porch light, so the back entry is dark, as well.

As one girl fumbles for her house keys in the dark and tries to find the keyhole in the door, a criminal creeps up from behind. He punches the other girl in the face, rips the necklace off her neck and runs away into the night, never to be seen again.

The crime occurred years ago. The teenager’s wounds healed, but the memory stayed with her.

That teenager was Mary Ellen Brown, who today is a business owner, a woman of achievement. Among other things, she is president of the Midway Chamber of Commerce.

The memory that long-ago night spurred her to invent what she calls the Door Halo—an easy-to-use device that at the very least provides convenience and at most could save a life.



The Door Halo is a ring-shaped LED light initially designed to fit around and adhere to the lock on a door. It is activated by motion, so when you’re ready to unlock the door, the light switches on and lights your way.

It automatically switches off after 30 seconds, but lights up again with just the wave of a finger.

It is powered by a long-lasting lithium ion battery, rechargeable via a micro USB cord included with each purchase. No tools are required for installation. It is lightweight (6 ounces) and adheres to doors via a magnetic ring or a peel-and-stick ring.

“This light has many useful applications, not just as a way to find to your way to the lock on your door,” Brown said. “I know people who use it as a nightlight in various rooms in their home. Others use it in their car or garage or workbench.”

It also could prove useful as an emergency light during a power outage, especially in situations like a fire where people need to find an exit quickly.

The Door Halo is available from Amazon, Walmart and other online retailers for about $39.99 and up. It may be purchased for less ($29.99) directly from doorhalo.com. A four-pack of the lights can be had for as little as $95.97.

It was a hit with consumers when it debuted, and sales are still brisk, Brown said.

“My hope is that people are fortunate enough to simply find this a convenience,” Brown added. “But should they ever be in danger and need a light instantly, they can rest assured that they have it.”
