On Halloween night, millions of small lights appear in the dark.
They glow from porches and windowsills, from carved pumpkins and paper lanterns, from candles flickering behind glass. Children follow them from house to house. Neighbors leave them burning as a sign that the door is open. For one evening, whole streets are lit with warm, golden light.
We rarely stop to ask why. But the tradition of lighting the darkness at the end of October is far older than plastic pumpkins and candy. It began with fires on hilltops, lanterns carved from turnips, and candles placed in windows to guide loved ones home.
This is the story of the Halloween lantern, and of why a small light in the dark has always meant so much more than light.
The Legend of Stingy Jack
The name "jack-o'-lantern" comes from an old Irish folktale about a man known as Stingy Jack.
According to the story, Jack was a clever and mean-spirited trickster. He invited the Devil to have a drink with him and then, not wanting to pay, convinced the Devil to turn himself into a coin. Instead of using the coin, Jack slipped it into his pocket next to a small silver cross, which kept the Devil trapped. He only let him go after the Devil promised never to take Jack's soul.
A Coal Inside a Turnip
When Jack finally died, the story says he was not allowed into heaven because of his wicked ways. And the Devil, keeping his promise, would not let him into hell either. Instead, he sent Jack off into the dark night with only a single burning coal to light his way.
Jack placed the coal inside a hollowed-out turnip and has been wandering the earth with it ever since. As the editors of History.com explain in their article on the Irish origins of the jack-o'-lantern, people began calling this ghostly figure "Jack of the Lantern," which was later shortened to "Jack O'Lantern."
From Turnips to Pumpkins
In Ireland and Scotland, families carved faces into turnips, potatoes, and other root vegetables and placed a candle or an ember inside. They set these lanterns in windows and near doorways on Halloween night.
A few of these early lanterns have survived. The National Museum of Ireland keeps a cast of a carved Halloween turnip, sometimes called the "ghost turnip," donated in 1943 by a schoolteacher from a village in County Donegal. With its pinched, angry little face, it looks very different from the friendly pumpkins we know today.
When Irish and Scottish families emigrated to America in the 1800s, they brought the tradition with them. In their new home, they discovered the pumpkin, a native American vegetable that was bigger, softer, and much easier to carve. Over time, the pumpkin became the classic Halloween lantern.
Why People Lit Lanterns on Halloween Night
The jack-o'-lantern is only one part of a much older story about light at the end of October.
For the ancient Celts, the festival of Samhain marked the end of the harvest and the beginning of the dark half of the year. People believed that on this night, the spirits of the dead moved through the countryside. Great bonfires were lit on hilltops, and families carried their flames home to relight the fires in their own hearths.
Light to Protect
Some lanterns were meant to frighten away wandering spirits. The scary carved faces of the turnip lanterns were designed to keep unwelcome visitors, like Stingy Jack, far from the door.
Light to Welcome
But light also had a gentler meaning. In many places, people believed that the spirits of their own loved ones might return home on this night. Candles and lanterns were lit to guide them back and to show that they were still remembered and still welcome. The same light that kept strangers away also called family home.
That double meaning, protection and welcome, is at the heart of every Halloween lantern still glowing today.
A Candle in the Window
Few symbols are as simple, or as moving, as a single candle glowing in a window.
In Ireland, families have long placed a lit candle in the front window, especially on Christmas Eve. The tradition is often traced back to a time when Catholic worship was forbidden, and a candle in the window quietly told a traveling priest that he would be safe and welcome inside. Over the centuries, it came to mean welcome for any traveler with nowhere to go. As IrishCentral describes in its look at Ireland's ancient Christmas traditions, the candle in the window is still lit in Irish homes today.
A Light for Those Far Away
For Irish families, the candle took on another meaning as millions of people emigrated to America and beyond. A light left burning in the window was a way of saying to sons, daughters, and friends across the ocean: we have not forgotten you, and there is always a place for you here.
In 1990, Mary Robinson, the President of Ireland, placed a light in the window of her official residence in Dublin as a symbol of remembrance for the Irish living abroad. It was a small gesture, but it moved people around the world.
Leaving a Light On for Love
The same idea lives on in many American homes. People leave a porch light on for someone coming home late, for a partner returning from a long trip, or for a child back from college. On Halloween night, a glowing porch light tells trick-or-treaters that they are welcome to knock. In every case, the message is the same: someone here is waiting for you.
Lanterns of Love Around the World
The connection between light and love is not only Irish or American. It appears in cultures all over the world.
China's Lantern Festival
In China, the Lantern Festival marks the end of the Lunar New Year celebrations with streets full of glowing lanterns under the first full moon of the year. In earlier centuries, it was also one of the very few nights when young unmarried women were allowed to go out in public. As CNN explains in its feature on China's Lantern Festival, this is why the festival is still known as one of China's Valentine's Days. Among the lanterns, many love stories began.
Lanterns were often hung with riddles written on paper, and people strolled from one to the next trying to solve them. For a young couple, guessing riddles together under the soft glow of the lanterns was a perfect, innocent excuse to talk, laugh, and get to know each other. Many classic Chinese poems from this time describe lovers meeting, or longing to meet, on the night of the lanterns.
Diwali: The Festival of Lights
In India and in Indian communities around the world, Diwali, the festival of lights, is celebrated each autumn with rows of small oil lamps and candles in every doorway and window. The lights welcome good fortune and celebrate the victory of light over darkness. It is also a time for giving gifts to family and friends, and in many families, it is a traditional time to buy gold, as a symbol of prosperity and blessings for the year ahead.

The Psychology of Firelight
Why does a flickering candle or a crackling fire make us feel so calm and connected? Science has some interesting answers.
Why Flames Calm Us
Anthropologist Christopher Lynn of the University of Alabama studied how people react to fire. In his research, people watched a fire with its natural crackling sound, and their blood pressure went down, especially the longer they watched. As the university reported in its summary of the study, campfires help lower blood pressure, and the effect was strongest in people who were more caring and social toward others.
Lynn believes that sitting around fires together may have helped early humans relax, talk, and form close bonds. In other words, we may be built to feel closer to each other in the glow of a flame.
Warm Light, Warm Feelings
Candlelight is soft and golden. It hides harsh shadows, makes faces look gentle, and turns an ordinary room into something intimate. That is why candlelit dinners have been a symbol of romance for so long. The light itself seems to slow time down.
A Light Shared Is a Bond
Every tradition in this story involves people gathering around light together: families by the hearth, neighbors on Halloween night, couples beneath lanterns. Light brings people in from the dark and draws them closer to one another.
Gold: The Color of Light
There is a reason gold has always been connected with light.
For thousands of years, gold has been the color of the sun, of fire, and of candlelight. In old churches and palaces, walls and frames were covered with thin layers of gold leaf so that they would catch the flickering light of candles and shine in the dark. Gilded candlesticks and lamps turned a small flame into a warm, glowing presence.
Gold also shares the most important quality of a light left burning in the window: it lasts. It does not rust, fade, or lose its glow. That is why, across so many cultures, gold has been chosen for the gifts that mark love and promises, gifts meant to keep shining long after the moment has passed.
Ways to Bring a Little Light to Someone You Love
This Halloween season, you can carry on one of the oldest traditions in the world with a few simple gestures.
Leave the Light On
If someone you love is coming home late, leave the porch light or a lamp in the window burning. It is a small way of saying, "I was thinking of you."
Set the Table by Candlelight
Turn off the bright lights, light a few candles, and place a few roses on the table. Red for passion, or golden and peach for warmth. It turns an ordinary dinner into a moment worth remembering.
Carve a Lantern Together
Carving a pumpkin is not only for children. Doing it together, laughing over the mess and lighting the candle at the end, connects you to a tradition that is hundreds of years old.
Give a Gift That Glows
Some of the most meaningful gifts are the ones that catch the light: a candle chosen with care, a lantern for the garden, or a piece of gold that shines every time the person you love looks at it. Like a candle in the window, a gift like this keeps saying "I am thinking of you" long after it has been given.
Conclusion: The Light That Waits for You
From Celtic bonfires to Irish turnip lanterns, from candles in windows to glowing pumpkins on American porches, people have always answered the darkness in the same way. They have lit a light.
Sometimes that light was meant to keep danger away. But more often, it was meant to bring someone home. It said: you are remembered, you are welcome, and someone is waiting for you here. It guided travelers, comforted families separated by oceans, and gave young lovers a chance to find each other beneath the lanterns.
This Halloween, when you see the pumpkins glowing and the candles burning in windows along your street, remember what those lights have meant for centuries. They are not just decorations. They are some of the oldest symbols of love we have.
A light in the dark has never been only about seeing the way. It has always been about letting someone know that they are loved, and that the way home is still open.
