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
Technicians and vehicle owners commonly look up rear lamps by OEM part numbers (e.g., 9653547580, 6350CA) to confirm fitment. Including these codes in listings increases findability and helps ensure the correct replacement is ordered.
Reason This Part Most Often Fails
The most frequent causes of failure are moisture ingress due to degraded seals or cracked lenses and physical damage from impacts. Corroded connectors and worn bulbs are also common, especially on higher-mileage vehicles or those exposed to harsh climates.
