American Idol winner David Cook today launched the “Light On” interactive lighter application for iPhone and iPod touch, giving fans a deluxe version of his first single, “Light On,” co-written by Chris Cornell and Brian Howe off his debut album. The “Light On” App is now available for download from Apple’s App Store on iPhone and iPod touch or at www.itunes.com/appstore/ and David Cook’s debut album will be released on 19 Recordings / RCA Records on November 18th on the iTunes Store.

The interactive “Light On” App turns an iPhone or iPod touch into a “virtual” lighter while playing Cook’s single “Light On.” Fans simply “flick” the iPhone or iPod touch and the flame goes out while the song fades out. The application also provides links to the iTunes Store to listen and buy Cook’s new hit single or pre-order his upcoming album.
