Lights Out was an American radio show devoted to horror and supernatural stories, providing listeners with a thrilling and eerie experience. The series, initially conceived as a midnight mystery serial, shifted to an anthology format emphasizing crime thrillers and the supernatural after its success. Created by Wyllis Cooper, the show's stories were characterized by grisly tales with dark, tongue-in-cheek humor. Lights Out was known for experimenting with advanced radio techniques, such as stream of consciousness and first-person narration. The program utilized distinct sound effects to enhance the horror experience, providing realistic simulations that were unique to the drama.

Debuting in 1934, Lights Out aired on various networks until the summer of 1947, eventually transitioning to television. The series is considered one of the earliest radio horror programs, predating Suspense and Inner Sanctum. Cooper's run on the show saw the creation of around 120 episodes, with the show continuing under the direction of Arch Oboler after June 1936. Chicago's pool of creative talent greatly benefited the show, and the series' sound effects were often carefully crafted and experimented with to achieve the desired result. Among the notable actors who participated in the series were Sidney Ellstrom, Art Jacobson, and Betty Lou Gerson.
