The center high mount stop light is the third brake light. It lights up together with the main brake lamps whenever the brakes are applied, which gives drivers behind you an extra signal that you are slowing or stopping.
Signs this part may need replacing include a cracked or broken housing, moisture inside the light, or a third brake light that stays dark while the other brake lights work. A wiring or connector fault can cause the same symptoms, so diagnose the cause first. If the light assembly itself has failed, the Dorman 923-401 replaces it. See the "Vehicles it fits" section for full vehicle details.
