Part description

This right rear fender lamp is designed for Citroën C3 II A51 and represents a suitable solution when replacing a damaged or non-functional rear light. It is an original Stellantis part for Citroën/Peugeot cars, which is especially important for proper seating, appearance and connection to the surrounding body parts.

The lamp is supplied without a bulb base, which can be purchased separately. The location of the part is on the side behind the passenger, i.e. the right rear part of the car in the fender. When looking for a spare part, it is often searched by production numbers, so we also include the exact designations 9673805380 and 6351KQ.

The used original car part is suitable for repairs after an accident, when the plastic breaks, leaks into the lamp or when the brightness is reduced. For auto mechanics and home repairs, the advantage is that the original design usually matches the original assembly better than non-original replacements.

Installation recommendations

Generally/typically for replacing the tail lamp in the fender, the exact procedure may vary depending on the specific design of the car. Below is a practical general procedure for this type of part.

1) Before assembly

• Check that the new used part matches the original part in shape, fit, orientation and connector.
• Compare the markings 9673805380 and 6351KQ with the old part if it is legible.
• Check the condition of the lamp cover, mounting points and sealing surfaces.
• Make sure the bulb socket is not included, as the documentation says it comes without a bulb socket.

2) Necessary tools and materials

• A common set of hand tools
• Screwdriver or gola set according to the type of attachment
• Plastic pry bar for removing trim covers
• Clean cloth
• Preparation for cleaning contact surfaces, if needed
• Protective gloves

3) Step-by-step assembly procedure

1. Turn off the ignition and secure the vehicle against movement.
2. Open access to the rear part of the lamp from the inside of the luggage compartment or from the hood area, depending on the car design.
3. Carefully remove any covers or trims that prevent access to the lamp mount.
4. Unplug the electrical connector or remove the bulb socket from the old lamp if used separately.
5. Unfasten the fasteners of the old lamp and carefully remove the part so as not to damage the paintwork or the surrounding plastics.
6. Check the contact surface of the bodywork and remove dirt, moisture or remnants of old pollution.
7. Compare the old and new lamp, including mounting, guide points and connections.
8. If the original bulb socket is used, refit it to the new lamp according to the design of the given version.
9. Place the lamp correctly in the fender and make sure it sits evenly without tension.
10. Tighten the fastening sufficiently so that the lamp is firmly held, but the plastic body is not damaged.
11. Reconnect the electrical connector or bulb socket.
12. Reinstall all covers and interior trim that were removed during disassembly.
• 4) Post-assembly checks and test drive/function verification
  • Check the function of all light modes used by the lamp.
  • Verify that the lamp sits correctly in the body and that there are no gaps between the part and the surrounding surfaces.
  • After a short ride, check that the part has not come loose and that there is no moisture in the lamp.

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

  • Swapping right and left side – always check that it is the part behind the passenger.
  • Overtightening – plastic parts may crack, so tighten with sensitivity.
  • Inaccurate lamp seating – check fit and alignment before tightening.
  • Omission of bulb socket – this part is without a socket, so make sure you have the necessary accessories before fitting.
  • Contaminated seating surface – dirt can cause poor seating or later leakage.

  Reasons why the part is damaged

  • Damage during parking or minor impact to the rear of the car
  • Cracking of the lamp cover due to mechanical impact
  • Leakage and subsequent deterioration of the lighting function
  • Plastic aging and loss of tightness
  • Damage to attachment points during careless disassembly
  • Vibration and long-term stress during vehicle operation
