WONDER LiGHT is the music video for the IDOLiSH7 song of the same name, and it is the fifteenth music video made for the IDOLiSH7 franchise. The song and parts of the video serve as the opening of the TV anime IDOLiSH7: Third BEAT! Part 2. The full video mostly uses scenes that do not appear in that opening sequence. A short OP version was streamed on September 17, 2022, before the anime began airing.
