Installation Recommendations

Installation is straightforward for experienced technicians. General steps:

• Access the rear lamp from inside the trunk or by removing the inner wheel-arch liner, depending on vehicle trim.
• Remove retaining screws or clips and carefully detach the lamp assembly, watching for plastic mounting tabs.
• Unplug the electrical connector and remove the old lamp. Fit the new lamp, connect the wiring and check alignment.
• Install bulb holders and bulbs if required, then test all light functions (tail, stop, indicator, reverse) before final reassembly.
• Always handle the lens carefully to avoid scratches. Replace any damaged mounting clips to ensure secure fitment.

Why This Part Fails

The most common causes of tail light failure are moisture ingress leading to condensation and corrosion of contacts, cracked or damaged lens from impacts, broken mounting tabs from stress or previous poor installations, and connector or wiring corrosion. Bulbs and bulb holders are also frequent failure points — note that this unit is supplied without bulb holders.
