Function And Typical Faults
The third brake light (Centre High-Mounted Stop Lamp – CHMSL) provides an additional, elevated brake signal to vehicles behind you. It complements the left and right brake lamps by increasing visibility, especially in heavy traffic or poor weather. Common reasons for failure include water ingress leading to corrosion, LED/module burnout, cracked lens or housing, damaged wiring or connector corrosion. Vibration and prolonged exposure to heat can also shorten service life.
How It Is Replaced
- Open tailgate and remove interior trim to access the lamp assembly (retain clips and screws).
- Disconnect the electrical connector and remove the securing screws or clips.
- Remove the old unit and fit the replacement, ensuring the sealing surface is clean and the gasket is intact.
- Reconnect the electrical connector, secure the lamp, reinstall trim and test the brake light operation.
- Typical Replacement Time: 15–30 minutes depending on experience and access to fasteners.
Recommended Installation
- Work In A Clean, Dry Environment To Prevent Moisture Trapping During Fitment.
- Inspect The Tailgate Seal And Mounting Area For Corrosion Or Damage; Replace Any Damaged Seals To Prevent Future Water Ingress.
