The phrase 'lights, camera, action' comes from film production, where it signals that the cameras are rolling and a scene is about to begin. Bass-boosted versions like this one take that familiar cue and push the low frequencies far louder, a style that became common in meme edits, gaming montages and short-form videos. This version is credited to Blue Square, whose loud, exaggerated take fits the trend of using heavy bass to make an intro feel dramatic. It remains popular because the phrase instantly tells viewers something is starting.
