How To Replace
- Open the tailgate and remove interior trim panels to access the lamp mounting screws.
- Unscrew the lamp retaining bolts and carefully pull the assembly outwards keeping an eye on the wiring harness.
- Disconnect the electrical connector(s) and, if present, remove bulb holders or LED modules.
- Fit the new lamp assembly, connect the wiring harness and test all light functions (brake, tail, indicator, reverse if applicable).
- Reinstall mounting screws and interior trim panels, ensuring all seals are correctly seated to prevent water ingress.
Installation Recommendations
- Turn ignition off before work and, if you will be handling wiring, disconnect the negative battery terminal to avoid short circuits.
- Handle bulbs with clean gloves to avoid oil contamination and premature failure (if replacing bulbs).
- Inspect and replace damaged mounting clips or sealing gaskets to ensure a secure, watertight fit.
- Apply a small amount of dielectric grease to electrical connectors to reduce corrosion and improve contact reliability.
- If the harness or socket is damaged, consider replacing the cable and socket set available separately to ensure long-term reliability.
Most Common Failure Reasons
- Impact Damage: Rear-end collisions crack the lens or break mounting tabs.
- Water Ingress: Failed seals allow moisture, causing corrosion of contacts or internal fogging.
- Corroded Connectors: Salt and moisture corrode sockets and wiring, causing intermittent or permanent failures.
- Bulb Or LED Failure: Bulbs burn out or integrated LEDs degrade over time (heat, vibration, or manufacturing tolerances).
- UV And Ageing: Plastic housings and lenses become brittle or discolored after years of exposure.
