The opening shot of a spinning car wheel and the "Britbox Original" logo.

The ad opens with a close-up of a car wheel spinning on a road, with the Britbox Original logo and 'In Association with BBC' displayed. It then cuts to a police officer in uniform, with five white stars and 'The Telegraph' text. Next, a police officer is seen in front of a car at night, with the text 'THE BEST COP SHOW' and 'The Guardian' logo. The scene shifts to a woman's blurred face in front of the same text. Finally, the title card 'BLUE LIGHTS' appears with 'NEW SEASON NOW STREAMING' below it, followed by the Britbox logo and tagline.
