Compatibility And Fitment

Installation Recommendations
Basic replacement steps for experienced technicians or competent DIY mechanics:
- Open the tailgate and remove interior trim panels to access mounting screws and electrical connector.
- Unscrew the retaining bolts and carefully release any clips holding the lamp in place.
- Disconnect the wiring harness plug and remove the old lamp assembly.
- Compare bulb sockets and gaskets; transfer bulbs if required or replace with recommended types.
- Install the new lamp, reconnect the harness, secure bolts and re-fit trim panels. Check alignment and seal seating to avoid water ingress.
Recommended precautions: Disconnect the battery before working on vehicle electrics to avoid short circuits. Inspect and clean connectors, use dielectric grease on terminals if necessary, and tighten fasteners to the manufacturer’s recommended torque to prevent damage to mounting tabs.
Most Common Reasons For Failure
- Water Ingress: Failed seals or cracked lens allow moisture, causing corrosion or short circuits.
- Impact Damage: Rear-end collisions or knocks commonly crack the lens or break mounting tabs.
- Connector Corrosion: Oxidation of contacts leads to intermittent or complete electrical failure.
- Bulb/Socket Wear: Repeated bulb changes and heat cycles can degrade sockets or holders.
- Aging Seals and Plastics: UV exposure and temperature cycles make housings brittle and leaky over time.
Notes For Professionals
When replacing a used lamp assembly, always check the integrity of the mounting points and the condition of the wiring harness. Align the unit correctly and test all functions (tail, brake, indicator, reverse where applicable) before returning the vehicle to service.
