Installation Recommendations
Recommended for installation by qualified technicians or experienced DIYers. Typical replacement steps:
- Park vehicle on level surface and ensure ignition is off.
- Disconnect the negative battery terminal to prevent short circuits during work.
- Open tailgate and remove interior trim panels to access mounting screws/bolts.
- Unscrew mounting fasteners, carefully pull the lamp assembly rearward and unplug the electrical connector(s).
- Fit the new lamp, connect the wiring harness and secure all fasteners to the manufacturer’s recommended torque values.
- Check and test all light functions (tail, brake, indicator, reverse, rear fog) before reassembling interior trim.
Use replacement gaskets or sealant where needed to ensure watertight fit. Replace any damaged clips or fasteners to maintain correct alignment and sealing.
Why The Part Commonly Fails
- Impact Damage: Rear collisions or knocks can crack the lens or break mounting points.
- Water Ingress: Damaged seals or cracked lenses allow moisture to enter, causing corrosion or electrical faults.
- Bulb Or LED Module Failure: Traditional bulbs burn out over time; LED modules can fail due to thermal stress or internal electronics degradation.
- Connector Corrosion Or Wiring Faults: Corroded pins or chafed wiring can interrupt signals and cause intermittent operation.
Service Life And Maintenance
There is no fixed replacement interval for the lamp assembly itself; replace when damaged, cracked, or when lighting functions are compromised. Bulb lifetimes vary by type—halogen/incandescent bulbs typically last a few years in everyday use, while LED modules usually offer longer life but may require full-lamp replacement if they fail.
Notes For Mechanics And DIY Enthusiasts
When ordering, use the product code 6351AC and the vehicle model designation to improve search accuracy. Inspect mounting points and wiring harness for hidden damage after a collision. If the lamp is replaced due to moisture or condensation, verify and renew seals to prevent repeat failures.
