The group will arrive on screens later in the autumn, playing characters who will eventually form a band within the show.
In real life, Daytona Lights formed back in 2009 after meeting at drama school in Hackney. They are currently signed to Hubris Records.
Speaking of his group's new role on Hollyoaks, lead singer Danny Lawrence commented: "It's a great opportunity for us to get our music out to a mass audience and that's what every musician wants.
"If people like it then that's a bonus and we are obviously enjoying the lifestyle Hollyoaks brings - everyone has been so welcoming."
Lawrence's bandmates are Matt Gill, Laurence Saywood, Sam Fordham and Louis Souyaye. All five will be playing characters who resemble their real-life selves.
A Hollyoaks statement said: "The boys all trained at critically acclaimed drama school East 15 so are no strangers to the acting world, and are set to play their way into the hearts of Hollyoaks fans everywhere as they launch into the limelight."
Daytona Lights will also be appearing on today's episode of The Hollyoaks Music Show, which airs at 8.55am on Channel 4.
