Why Lightsticks Are Important in K-pop
In most music genres, fans show support by cheering, waving signs, or singing along. In K-pop, however, the lightstick has become one of the most recognizable symbols of fandom culture.
These glowing devices are much more than concert accessories—they represent identity, community, technology, and the unique bond between artists and their fans.
From Balloons to Bluetooth: A Brief History
Lightsticks didn’t start out as the sleek, app-connected devices fans carry today. Back in the late 1990s and early 2000s, fandoms simply brought matching balloons or plain glow sticks to performances, using color alone to signal which group they supported.
Over time, those balloons gave way to simple battery-powered glow sticks printed with a group’s name, and eventually to the custom-shaped, Bluetooth-enabled “bongs” fans know now. What began as an improvised way to stand out in a crowd has grown into a defining piece of K-pop visual culture—and a serious business in its own right.
A Symbol of Fandom Identity
Every major K-pop group has its own official lightstick, usually designed with colors, shapes, and symbols that reflect the group’s concept and its fandom’s name. Owning one is a way for fans to proudly display their loyalty and connection to a particular artist.
BTS fans (ARMY) carry the globe-shaped “ARMY Bomb,” while BLACKPINK’s fandom (BLINK) waves the hammer-shaped “Bl-ping-bong,” a design the members themselves helped create after Jennie joked about being hit with a toy hammer on a variety show.
Other fandoms have their own equally personal designs: SEVENTEEN’s “Carat Bong” is named after the group’s fandom CARAT and colored in rose quartz and serenity; Stray Kids’ “Nachimbong” features a spinning “compass without direction,” a nod to the group’s debut storyline about finding their own path; TWICE’s “Candybong” was inspired by their song “Candy Boy” and doubles as a bedroom mood lamp; and Mamamoo’s radish-shaped “Moomoobong” was even designed with vibration features to include fans with limited hearing or eyesight.
These instantly recognizable shapes let fans identify each other within the larger K-pop community at a glance.
Creating a Sea of Light
One of the most breathtaking sights at a K-pop concert is the synchronized ocean of light filling an arena. Thousands of fans waving matching lightsticks create a visually stunning experience that enhances performances and strengthens the atmosphere.
This effect is no accident. Since BTS introduced Bluetooth connectivity to the ARMY Bomb in 2017, most major groups’ lightsticks can now pair with a venue’s central control system, letting concert staff change colors and patterns across the entire crowd in real time.
TWICE’s newest “Candybong ∞” even uses an LED ring and mirrored surfaces to create a layered, tunnel-like glow effect. As technology advances, the lightsticks themselves keep evolving—BTS released a fourth-generation ARMY Bomb in 2026 with swappable parts and a companion app that doubles as a home mood lamp, while older versions are gradually phased out of venue synchronization. The result transforms the audience into part of the show itself, creating moments that are unforgettable for performers and fans alike.
Strengthening the Artist-Fan Connection
K-pop agencies place a strong emphasis on the relationship between idols and their supporters, and lightsticks serve as a visible reminder of that bond. When artists look out into the crowd, they see not just individual fans but a unified, glowing community supporting them.
Idols have spoken often about how moving it feels to see their fandom’s lights shining during concerts, especially during emotional songs or milestone shows—a moment that turns thousands of individual fans into one visible, collective presence.
A Collectible Piece of K-pop History
Lightsticks evolve constantly. New versions are released as groups grow, change concepts, or mark anniversaries, and each one becomes a small artifact of a particular era. BTS alone has gone through four major versions of the ARMY Bomb since 2015, plus a Special Edition released in 2020, each with its own design quirks and technical upgrades.
BLACKPINK’s lightstick has seen two standard versions plus a special edition released in 2025, and SEVENTEEN marked their tenth anniversary with a dedicated edition of the Carat Bong. Because of this constant evolution, lightsticks become genuinely valuable collectibles that mark different chapters of a group’s career.
Long-time fans often keep older versions as souvenirs rather than upgrading every time, creating a personal timeline of their journey with a favorite artist—a shelf of glowing history that says as much about the fan as it does about the group.
Bringing Fans Together
The importance of lightsticks extends well beyond the concert hall. Fans bring them to fan meetings, music festivals, public events, and even online watch parties. They help create a sense of belonging among people who may come from entirely different countries, cultures, and backgrounds but share the same passion for one artist.
In many ways, a lightstick functions as a membership badge. Spot one in an airport, on a subway, or at a convention, and it instantly connects strangers through a shared fandom—no introduction necessary.

Supporting Artists Financially
Official lightsticks are also an important source of revenue for entertainment companies and the artists themselves. Fans generally prefer buying official merchandise because it directly supports the groups they love rather than third-party knockoffs, and entertainment companies have leaned into this: limited editions, anniversary releases, and tour-exclusive versions routinely sell out and become sought-after items in resale markets.
Lightsticks now sit alongside albums and photocards as one of the cornerstone categories of K-pop’s broader merchandise economy, contributing meaningfully to agencies’ bottom lines year after year. Some companies have even begun adding authentication features—like companion apps or embedded chips—to verify official lightsticks and protect that revenue from counterfeits.
More Than Just Merchandise
While they may look like simple glowing sticks, lightsticks have become an essential part of K-pop culture.
They represent fandom pride, create unforgettable concert experiences, strengthen the bond between artists and supporters, and serve as lasting souvenirs of a fan’s journey. From their humble origins as colored balloons to today’s Bluetooth-connected, app-controlled devices, lightsticks have tracked the growth of K-pop itself—becoming more sophisticated as the industry has gone global.
In a genre built on community and engagement, the lightstick is far more than merchandise. It’s a symbol of belonging, held in the hand of every fan who has ever wanted their favorite artist to know they were there.
