Installation recommendations
Generally/typically for rear exterior light replacement (exact steps may vary depending on the specific car model):
1) Before assembly
- Compare with the old piece shape, side (right) and attachment.
- Check the condition of the gaskets of the seating surface and mounts – cracked mounts are often the cause of leaks and vibrations.
- Make sure you have a bulb socket (this part is without a socket).
2) Necessary tools and materials
- Normal set of hand tools (typically a ratchet/nut or screwdriver depending on the attachment)
- Plastic crowbars for removing upholstery/covers (for gentle work)
- Cleaning agent and cloth for contact surfaces
- Dielectric vaseline for contacts (optional)
3) Step-by-step assembly procedure
- Turn off the ignition and lights.
- Open the trunk and access the lamp mount (typically after flipping/removing the trim section).
- Disconnect the electrical connector from the socket/installation.
- Undo the light fasteners (nuts/bolts depending on design).
- Carefully remove the lamp from the body – do not pull on the wiring, watch the guide pins.
- Clean the landing surface on the body and check for damage.
- Move the base with bulbs (if it is part of the old light) into the newly installed lamp, or place it back according to the design.
- Sit the new right rear light into the hole and check for proper seating and alignment.
- Tighten the fasteners evenly – so that the light fits, but without switching the mounts.
- Connect the electrical connector.
- Refit the boot trim/covers.
- Turn on the lights and verify the function of all light modes according to the placement of the bulbs.
-
4) Post-assembly checks and test drive/function verification
- Check that the lamp is tight and there is no play.
- Verify that there are no visible gaps between the lamp and the body and that the gasket is seated properly.
- After the first ride, check that the light has not come loose and that there is no moisture inside.
5) The most common assembly mistakes + how to avoid them
- Bad gasket seating → clean the seating surface and check the fit before tightening.
- Connector/cabling damage → disconnect/connect the connector by the body of the connector, not by the cables.
- Replacing the base/bulbs → compare the arrangement and function of the lights before fitting.
- Accident or light tapping – cover cracking, brackets breaking.
- Vibration and fatigue of the material – gradual cracking of the attachment, especially with poor tightening.
- Leaks and condensation – damaged seals or cracks lead to moisture inside the lamp.
- Unprofessional disassembly/assembly – broken guide pins, cracked handles, damaged connector.
