Installation Recommendations
Before starting work always disconnect the vehicle battery. Access the lamp from inside the trunk by removing the trim panel to reach the retaining screws and electrical connector. Remove the fasteners, unplug the connector and withdraw the lamp assembly. Transfer bulbs if required and check the condition of the gasket or sealing strip; replace if degraded. Fit the new unit, secure fasteners evenly and reconnect the connector. Reconnect the battery and test all light functions (tail/position, stop, indicator, reverse if applicable). Ensure the lens sits flush and the seal is intact to prevent water ingress. Tighten fasteners to manufacturer torque where specified.
Why This Part Most Often Fails
Tail lamps typically fail due to external factors: impact or collision damage, moisture ingress that leads to corrosion of contacts or bulbs, cracked lenses from stress or heat, and degraded seals that allow condensation. Electrical issues such as corroded connectors or damaged wiring can also cause intermittent operation or complete failure. Regular inspection of seals and electrical contacts helps prevent premature failure.
