Is your interior lamp cracked or missing altogether? Replace it with a new one and give yourself plenty of light in the cockpit when your 911 blows a fuse. See also 911 & Carrera Lights and Lenses. The original interior lamps with the chrome trim around the edges are no longer available, however, the later-style ones with black trim (originally used on the 1984-89 911 Carreras) are a direct replacement.
