Detailed Description
Motormite 85879 is a replacement side marker light socket for select Chevrolet, Buick, Cadillac, Oldsmobile, and Pontiac vehicles. It is commonly used on applications such as the Chevrolet Corvette, Buick Regal, Buick Roadmaster, Chevrolet Caprice, and Pontiac Grand Prix where a 2-wire straight, short socket with quarter-turn retention is specified.
