Installation Recommendation

• Safety First: For work on electrical connections it is recommended to disconnect the negative battery terminal to avoid short circuits. Take care not to damage trim or lamp clips during removal.
• Access: Remove or open the rear lamp assembly from the wing (access via boot or inner wing liner depending on model year) to reach the bulb holder.
• Replacement Steps: Unplug the lamp connector, release the retaining tabs on the old holder, remove the holder and replace with the new unit including the pigtail. Ensure the holder seats correctly and retaining clips engage.
• After Installation: Reconnect the wiring, test all rear light functions (tail, brake, indicator, reverse if applicable) and verify there is no play or water ingress at the mounting point.
• Good Practice: Inspect bulb condition and socket contacts when replacing—clean contacts or replace bulbs if signs of overheating or corrosion are present.

Why The Part Commonly Fails

• Corrosion of electrical contacts due to moisture ingress is the most frequent cause of failure, leading to intermittent lighting or open circuits.
• Heat damage from high-wattage bulbs or poor contact can melt or deform the plastic socket and contacts.
• Mechanical stress or brittle aging of plastic (UV exposure, vibration) can crack retaining tabs and cause poor retention in the lamp housing.
• Damaged wiring or connector pins from previous repairs or incorrect handling during lamp removal.

Fitment And Replacement Procedure

1. Park vehicle on a level surface and disconnect the battery before starting work to avoid short circuits.
2. Open tailgate and remove the rear trim panel or inner wheel-arch lining to access the lamp fixing screws/bolts.
3. Unscrew the fasteners securing the lamp to the wing. Carefully pull the lamp assembly outward to avoid damaging the paint.
4. Unclip the electrical connector and remove the lamp. If the socket and bulbs are separate, unclip the bulb holder from the lamp.
5. Fit the replacement lamp, reconnect the electrical connector, and secure the assembly with the original fasteners. Check sealing surface and replace any damaged gasket to prevent water ingress.
6. Reconnect the battery and test all lamp functions (tail, brake, indicator, reverse if applicable) before refitting trim panels.

Installation Recommendations

– Always disconnect the battery before removing or installing the lamp to protect vehicle electronics and prevent accidental shorts.
– Use correct sized hand tools and avoid overtightening screws to prevent cracking the lamp housing.
– Inspect and, if necessary, replace the rubber gasket or seal to ensure watertight installation.
– If the bulb holder is corroded, replace it together with bulbs to ensure reliable electrical contact.
– After installation verify all lighting functions and ABS/airbag dashboards for fault codes; clear codes if necessary following manufacturer procedure.

Why This Part Most Often Fails

– Collision Damage: The most frequent cause of lamp replacement is impact damage to the rear wing in minor accidents.
– Water Ingress: Cracked lens or deteriorated seals allow moisture inside, causing corrosion of the bulb holder and connectors.
– Connector Corrosion And Wear: Corroded pins or worn bulb sockets lead to poor contact, flickering or intermittent lighting.
– UV And Weathering: Over time, exposure to sun and road debris can crack or cloud the lens, reducing light output and structural strength.
