Seventies slang for a police car, from the television show Adam
12.
Adam refers to a two-person unit of the LAPD and the
12 to the fictional 12th district.
“Must be because I had the flu for
Christmas and I’m not feeling up to
par./It increases my paranoia, like looking in my
mirror and seeing one of those damn lit-up Adam-12s.”
—David Crosby, “Almost Cut My Hair,” live, 1974
