K.I.T.T. first appeared in Knight Rider, the American television series that ran from 1982, as Michael Knight's artificially intelligent partner car. Voiced by William Daniels, the black Pontiac Trans Am became a pop-culture icon for its scanner light, dry wit and ability to drive itself. Clips of its distinctive sound have circulated online for years among fans of retro television, car culture and 1980s science fiction, and the short length makes it easy to reuse as a quick nostalgic cue in memes and edits.
