From 1984-93 Chevrolet delivered the underhood lamp lenses in plastic. Unfortunately the plastic lenses yellowed and cracked. In 1994 GM upgraded their lens to glass and eliminated the problems of the earlier models. Now you can replace cracked or missing lenses on 1994-94 models and upgrade 1984-93 models with glass using this all new underhood lamp lens. Simply remove the two retaining screws from the original and reassemble. Your Corvette’s underhood light can now do the job it was intended to do.
