he K-pop lighstick is literally a light stick that represents a K-pop group. Each group has its own lightstick with its own colors and characteristics. Fans can support and show their love for their favorite groups.
They call lightsticks "eungwonbong" in Korean, which is "support (as in cheering) stick" if translated literally, so a lot of lightstick names include "bong" (stick) in them.
