How It Works And When To Replace
The Third Brake Light Houses LEDs/Light Elements And Serves As A Center High‑Mount Stop Lamp (CHMSL), Providing An Additional Brake Signal Visible To Vehicles Behind. It Should Be Replaced If The Light Fails To Illuminate, If The Lens Is Cracked Or Distorted, Or If There Is Evident Water Ingress Or Corrosion At The Connector. Always Inspect The Supply Cable And Connector Before Replacing The Lamp—A Faulty Wiring Harness Or Damaged Connector Can Cause A New Unit To Appear Defective.
How To Replace (Typical Procedure)
- Park The Vehicle On A Level Surface And Disconnect The Battery Before Starting Work.
- Access The Lamp From Inside The Tailgate/Rear Hatch By Removing Interior Trim Panels Or Fasteners.
- Disconnect The Electrical Connector And Remove Securing Screws Or Clips Holding The Lamp To The Tailgate.
- Swap The Old Lamp For The New Unit, Reconnect The Electrical Connector, Seal Any Grommets If Needed, And Refit Interior Trim.
- Reconnect The Battery And Verify Full Function Of Brake Lights (Brake Pedal Depressed And Handbrake/Lighting Checks Where Applicable).
