Installation recommendations

Generally/Typically Applies to rear lamp bulb socket replacement; the exact steps may vary depending on the particular design of the lamp.

1) Before assembly

• Compare the new and original socket: shape, locks/packs, connector position and bulb placement.
• Check the socket contacts (oxidation, burning, deformation). Light pollution should be cleaned.
• Please note that the functionality of the bulbs themselves is not guaranteed – it is recommended that the bulbs be checked and replaced if necessary.

2) Necessary tools and materials

• Basic set of screwdrivers/bits (depending on the cover design and attachment)
• A clean cloth or electrical contact cleaner
• Protective gloves

3) Step-by-step assembly procedure

1. Turn off the ignition and lights.
2. Open access to the rear lamp (typically after removing the boot cover/trim or service cover).
3. Disconnect the electrical connector from the socket (release the connector lock, do not pull on the wiring).
4. Release the base from the lamp (by turning/unlocking the locks depending on the design) and carefully remove it.
5. Remove the bulbs from the original socket and check their condition (filament, blackening, loose socket).
6. Check the contact surfaces and contact points in the lamp, or clean them carefully.
7. Install the bulbs in the new socket in the same layout as the original part.
8. Place the base back into the lamp and secure it with the locks so that it sits straight and without tension.
9. Connect the electrical connector and check that it clicks properly.
10. Before completely covering the access, turn on the lights and verify the function of the individual modes (contour, brake, turn signal, reverse/fog depending on the equipment).
11. Refit the covers/trims.

• 4) Post-assembly checks and test drive/function verification

  • Verify that all taillight functions light up steadily and without dropouts when wiring moves.
  • Check that the connector and cables are not under tension and that nothing is touching sharp edges.

  5) The most common assembly mistakes + how to avoid them

  • Replacing the positions of the bulbs → take a photo of the original installation before disassembly.
  • Poorly engaged connector → after connecting, gently pull the connector to see if it holds on the fuse.
  • Oxidation of the contacts → clean the contacts and check the pressure; you will prevent blackouts.
  • Socket failure → seat the base evenly; crooked seating often leads to bad contact.

  Reasons why the part is damaged

  • Oxidation and contamination of contacts (moisture, condensation in the lamp) → impaired contact and heating.
  • Thermal stress from light bulbs → deformation of the plastic or burning of the contacts.
  • Vibration and fatigue of the material → cracks in the socket, holding the bulb is allowed.
  • Reckless handling when changing light bulbs → broken locks, damaged connectors.
