With a National Television Awards nomination for Best New Drama and a slew of five star reviews, 2023 was a good year for Blue Lights.
Set in Belfast, the BBC One drama followed a batch of new constables as they navigated policing in a post-conflict Northern Ireland.
Before the first series ended its run, a second had been commissioned.
The brainchild of Declan Lawn and Adam Patterson, the writers and directors said they were excited for season two.
"Blue Lights is a very personal project for us, set in the city where we live, so for us making this show is a special kind of privilege," they said.
"In series two we join our officers exactly a year after the events of series one, and now they're facing a whole new set of professional and personal challenges."

Where is Blue Lights filmed?
The police drama is filmed in and around Belfast.
For months in summer 2023 you could see location signs attached to lampposts around the city with "BL 2" pointing in various directions.
Camera crews could be seen in the city centre in High Street and the production was also spotted in Dundonald, just east of the city.
And it seems co-creator Lawn may even appear in front of the camera in this series.
The former BBC News reporter and presenter posted on social media that his acting skills had been required.
