BIGBANG Unveils 20th-Anniversary Official Light Stick Ahead of ‘XX : COSMOS’ Tour

BIGBANG has revealed a new version of its official light stick, marking the group’s 20th anniversary with a refreshed piece of fan merchandise. A teaser released at midnight on August 5 KST gave viewers an early look at the redesigned item, which is being introduced alongside preparations for the group’s upcoming XX : COSMOS world tour.

The reveal places one of K-pop’s most recognizable concert accessories at the center of BIGBANG’s anniversary plans. Official light sticks have become a familiar part of the live-show experience, allowing fans to take part visually in a performance while also carrying a distinct symbol of the artist they support.

A new look for an anniversary year

The short teaser focuses on the updated design, presenting the new light stick as a commemorative release rather than a routine merchandise refresh. Its arrival during BIGBANG’s 20th-anniversary year gives the product an added role: it is both a practical concert item and a marker of a long-running connection between the group and its audience.

For a group with a history stretching across multiple eras of K-pop, an anniversary edition naturally carries extra interest. The new design brings a current visual treatment to an item closely associated with fandom culture, while retaining its purpose as a shared object for concerts and official events.

Details such as pricing, sales timing, regional availability and technical features were not included in the initial teaser. Those points will matter for fans planning to attend shows or add the anniversary item to their collections, but the first video was aimed squarely at introducing the design itself.

Connecting merchandise and the live stage

The timing also connects the new release to XX : COSMOS, BIGBANG’s forthcoming world tour. At large K-pop concerts, synchronized lights can turn an audience into part of the visual production, filling an arena with colors and patterns that complement the artists onstage. A newly issued official light stick is likely to be a visible part of that setting.

Beyond its use at performances, the item gives the anniversary campaign a physical focal point. Tour announcements, new music and special events often move quickly, while a concert light stick remains a lasting reminder of a particular period in an artist’s career. For longtime followers, that can make an anniversary version especially meaningful.

The teaser’s release is also a reminder of how fan merchandise has evolved. What began as simple glowing accessories has developed into a major design category in K-pop, with each group’s official item functioning as a recognizable emblem at concerts, in photographs and across social media. Anniversary editions add another layer by linking that emblem to a specific milestone.

What comes next

BIGBANG has so far shared the first visual introduction to the 20th-anniversary light stick. More information is expected to clarify how the item will be sold and how it may be used during the XX : COSMOS tour. Until then, the reveal offers fans an early sign of the group’s approach to celebrating two decades in music.

As the tour moves closer, the redesigned light stick will likely become one of the most immediate ways for audiences to take part in the anniversary moment. Its unveiling combines a familiar concert tradition with a forward-looking design, setting the stage for BIGBANG’s next chapter of live performances.
