Part description

The used rear light bulb holder with a section of wiring is used to secure the bulbs and connect them electrically to the vehicle’s wiring system. It is a suitable solution if the bulb holder, contacts, or rear lamp connection is damaged, provided the light housing itself is still usable.

The information provided lists the part for the right and left rear lamps. When selecting a part, compare the markings 9820555080 and 9819649280, the shape of the holder, the contact layout, and the connector with the original part. The included section of wiring may make it easier to repair a damaged connection; its use depends on the condition of the wiring and the specific vehicle configuration.

Installation recommendations

The following procedure generally applies to this type of part. The exact method for accessing the rear lamp, releasing the holder, and connecting the wiring depends on the specific vehicle model and configuration. Follow the manufacturer’s service procedure.

1) Before installation

• Compare the product numbers, holder outline, fasteners, bulb positions, and connector design with the old part.
• Inspect the used part: the plastic must not be cracked or melted, the contacts must not be heavily corroded, and the wires must not have damaged insulation.
• Check the included section of wiring, especially the wire ends, their connections, and any signs of overheating.
• Also check the condition of the lamp and its seal. If water is getting in, replacing the holder alone will not resolve the cause of the problem.
• The supplied information does not confirm that bulbs are included. If transferring bulbs, inspect them and use only the type specified for the lamp in question.

2) Tools and materials required

• Standard hand tools suitable for the lamp fasteners and, if needed, a plastic trim removal tool for releasing covers.
• Gloves, a clean cloth, and a product suitable for cleaning electrical contacts and surrounding plastic.
• A multimeter for basic checks of the electrical connection.
• If wiring repairs are necessary, suitable tools and materials for professional, insulated connections protected against moisture.

3) Step-by-step installation procedure

1. Park the vehicle safely, secure it against movement, switch off the ignition and lights, and allow the bulbs to cool.
2. Before disconnecting the electrical system, follow the manufacturer’s instructions for disconnecting it safely; if disconnecting the battery, follow the vehicle’s prescribed procedure.
3. Access the rear lamp according to the service procedure. Release covers and fasteners without using force.
4. Note the wiring routing and original connections. Release the connector lock and pull it out by the connector body, not by the wires.
5. Depending on the lamp design, release its fasteners or the bulb holder retainer directly. Remove the old holder without damaging the surrounding plastic or any seal.
6. Inspect the inside of the lamp, the mating surfaces, and the vehicle connector. Before continuing, address the cause of any moisture, contamination, or overheating.
7. Compare the two holders again. If transferring bulbs, check their condition and fit them into the corresponding positions without applying excessive force.
8. Based on the condition of the wiring, decide whether the original connection can be retained or the included section of wiring needs to be used. Do not connect wires based on color alone; the connections must match the wiring diagram for the specific vehicle. Have a professional repair the wiring if you do not have the appropriate equipment and experience.
9. Fit the replacement holder into the lamp, check that any seal is seated correctly, and secure all fasteners.
10. Connect the connector, check that it is secured, and route the wiring so that it is not stretched, pinched, or in contact with sharp edges. Reinstall the parts that were removed.
11. Restore power according to the manufacturer’s procedure and check all lighting functions of the relevant rear lamp.

4) Checks after installation and function verification

• With the vehicle stationary and secured, test all functions incorporated in the lamp, including their normal combinations. Have another person assist when checking the brake lights.
• Look for flickering, dim illumination, or other bulbs lighting up unexpectedly, as this may indicate a connection problem.
• Check that the lamp is securely seated, the connector is secured, and the wiring is routed freely without being pinched.
• If you notice a smell of overheating or irregular lighting operation, switch it off immediately and resolve the problem. A test drive does not replace checking all lighting functions before driving.

5) Most common installation mistakes and how to avoid them

• Leaving a damaged connector in place: an overheated or loose mating connector can also damage the replacement holder. Check both sides of the connection.
• Mixing up the wires: when using the included wiring section, follow the wiring diagram, not just the insulation colors.
• Using unsuitable bulbs: follow the specification for the specific lamp to prevent incorrect operation or excessive heating.
• Insufficient sealing: check the mating surfaces and the condition of any seal before closing the lamp.
• Forcing the holder or connector into place: if you encounter resistance, check the orientation and confirm that the parts match; do not force them past the retaining features.

Reasons why the part gets damaged

The following are common causes of damage to rear light bulb holders. They do not describe the condition found on this specific part.

• Moisture and water entering the lamp, which lead to contact corrosion and a deterioration in the electrical connection.
• Loose or oxidized contacts, which cause contact resistance and subsequent localized overheating.
• Unsuitable bulbs, which may subject the holder to more heat than it is designed to withstand.
• Mechanical stress when replacing bulbs, forcibly releasing the connector, or pulling on the wiring.
• Aging of the plastic and wire insulation due to temperature changes and prolonged use.
• Improper repairs to the electrical system, particularly loose connections or inadequate protection against moisture.
