The initial Britbox Original logo and the intense police-related visuals.

The ad opens with a Britbox Original logo and a BBC association logo. It then shows scenes of police officers, including one leaning against a door and another in a close-up shot. There are quick cuts to a car wheel on a road, a person holding a glass, and a man with a shocked expression. The pacing is fast, with quick cuts and dynamic camera angles. The ad features quotes from The Telegraph, The Guardian, and Los Angeles Times, highlighting the show's critical acclaim. It concludes with the title card for 'Blue Lights' and the Britbox logo.
