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.

Function And Fitment

The lamp is intended for the left (driver) rear quarter and provides the required rear lighting functions for safe road use. It is a body-mounted tail lamp (fender-mounted) and is matched to the original mounting points and electrical connector to ensure correct fit and easy replacement in vehicles that use the listed part numbers.

Common Failure Modes

• Moisture Ingress: Seal deterioration or cracked lens allows water into the housing, causing corrosion of contacts and bulbs or condensation that reduces light output.
• Impact Damage: Bumps or minor collisions can crack the lens or deform the mounting tabs, compromising fit and sealing.
• Socket And Wiring Corrosion: Oxidation of bulb sockets or connector pins leads to intermittent or failed circuits.
• Bulb Failure: Incandescent bulbs wear out over time; LED modules (if fitted) can fail due to thermal or electrical stress.

Recommendations For Installation

• Safety First: Disconnect the battery before starting to avoid short circuits. Follow vehicle manufacturer procedures for safe removal and installation.
• Removal: Access the lamp from inside the luggage area or by removing the interior trim to reach screws and the connector. Unscrew mounting fasteners and carefully release retaining tabs to avoid damage.
• Electrical: Unplug the multi-pin connector and inspect pins for corrosion. Clean or replace corroded terminals before fitting the new unit.
• Sealing: Check and, if needed, renew the sealing surface or gasket to prevent future moisture ingress. Ensure the lamp sits flush and fasteners are tightened evenly.
• Testing: Reconnect the battery and test all lighting functions (tail, brake, indicator, reverse where applicable) before reassembling interior panels.
• Spare Parts: Use original-style fasteners and retainers; damaged mounting tabs can be reinforced or replaced to ensure correct alignment.

Why This Part Is Searched By Code
