Installation recommendations

Generally/typically for rear lights and fog lights, they change as a whole and the match of the mount, connector and socket type is decisive. The exact steps may vary depending on the specific design of the car.

1) Before assembly

• Compare the new and original part: shape, attachment, connector, socket and seat in the body.
• Check the condition of seals and contact surfaces (leakage prevention).
• Check the socket and bulb – as bulb functionality is not guaranteed, a test or replacement is recommended.
• Visually check for cracks, broken handles and damage to the connector.

2) Necessary tools and materials (in general)

• Basic set of screwdrivers / gola
• Plastic crowbar for removing upholstery/covers (for work without damage)
• Contact cleaner (optional)
• Cloth for cleaning contact surfaces

3) Step-by-step assembly procedure

1. Turn off the ignition and lights.
2. For safety, disconnect the battery (especially recommended for electrical parts).
3. Get access to the tail lamp (typically after flipping/removing the boot cover).
4. Disconnect the electrical connector/socket from the light.
5. Remove the light fasteners (nuts/screws/fuses – depending on the design).
6. Carefully remove the light from the body so as not to damage the paintwork or guide pins.
7. Clean the bearing surface and check the seal.
8. Place the replacement left rear fog lamp correctly in position.
9. Tighten the fasteners evenly (without force, so that the plastic does not crack).
10. Connect the socket/connector and check that the latches are properly engaged.
11. Refit the covers/upholstery.
12. Connect the battery.
• 4) Post-assembly checks and function verification
  • Test the function of the rear fog lamp and check that the light shines steadily.
  • Check that the light fits well and there are no gaps anywhere.
  • After the first rain or wash, check that there is no moisture/fogging inside the light.

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

  • Damage to the seal → always clean the contact surface and do not pinch the seal.
  • Poorly engaged connector/socket → after connection, gently check that it holds and there is no play.
  • Leaving the old defective bulb → test the bulb in advance or replace it immediately.

  Reasons why the part is damaged

  • Cracking of the cover after impact or careless handling.
  • Leaking due to a damaged seal or poor fitting of the light.
  • Broken mounts due to vibration or overstretching of fasteners.
  • Corrosion/oxidation of contacts in socket and connector (moisture, age).
  • Damage to sockets/sleeves by heat or unsuitable light bulb.
