Blue Lights is a Northern Irish police procedural television drama series set in the fictional Blackthorn police station in Belfast, Northern Ireland, where the series was filmed. Created and written by Declan Lawn and Adam Patterson, it began broadcasting on BBC One on 27 March 2023. The first series followed three probationary police officers of the Police Service of Northern Ireland and the experienced officers who train, mentor, and work with them, with the second following the same characters a year later trying to quell a loyalist feud in the city. Both series of Blue Lights received critical praise and high viewership. A third and fourth series have been commissioned.
