Function And Features
This left rear lamp houses the circuits for tail light, stop light, turn indicator and reversing lamp. The unit is supplied without bulb sockets and without the black external cover trim. It is intended as a direct replacement housing — transfer any mounting brackets or seals from the original unit if required, or replace them for optimal sealing.
Installation Recommendations
1. Remove interior tailgate/trunk trim to access mounting bolts. 2. Unscrew lamp retaining bolts and carefully unclip the lamp from the body, then disconnect the wiring harness. 3. Transfer any original gaskets/seals or fit new seals to ensure watertight installation. 4. Install bulb sockets and bulbs (sold separately), connect harness and test all lamp functions before final tightening. 5. Align the lamp, tighten fasteners to the manufacturer’s specification, and reinstall trim. Use dielectric grease on bulb contacts to reduce corrosion and ensure reliable electrical connection.
Why This Part Fails Most Often
Rear lamps commonly fail due to physical impact (bumper or loading damage), cracked lenses allowing water ingress, degraded seals that permit moisture, corroded bulb sockets or contacts, and broken mounting tabs from vibration or improper removal. UV exposure can also fade reflectors and lenses over many years, reducing light efficiency. Regular inspection of seals and socket contacts extends service life.
Notes For Installers
• Bulb Sockets Not Included: Order the correct socket types and bulbs when replacing the lamp.
• Check Mounting Tabs: If original mounting tabs are damaged, replace or repair them to prevent loosening.
• Test All Functions: Verify tail, brake, indicator and reverse lights operate correctly after installation.
