Function

The socket secures the bulb in the rear right lamp assembly and provides the electrical connection between the lamp filament/LED module and the vehicle wiring harness. It ensures stable contact, correct bulb positioning and helps prevent short circuits or intermittent connections caused by corrosion or damaged terminals.

Common Failure Modes

This part most frequently fails due to water ingress and corrosion of the contacts, heat damage from an improperly seated or overloaded bulb, mechanical cracking from impact or repeated removal, and insulation wear leading to short circuits. Symptoms include flickering lights, intermittent operation, or complete loss of one or more rear lamp functions.

Installation Recommendations

Recommended for installation by experienced technicians or competent DIYers. Typical replacement steps:

1. Park the vehicle on a level surface and switch off the ignition.
2. Disconnect the negative battery terminal to avoid short circuits when working with rear lamp wiring.
3. Remove the interior trim or access panel in the boot to reach the lamp assembly fasteners.
4. Unscrew and gently withdraw the lamp unit from the wing to access the bulb holder.
5. Unplug the old socket from the vehicle connector and remove any damaged wiring or retained clips.
6. Fit the new bulb holder, connect the supplied wiring section to the vehicle loom using the original connector or approved splicing method, and secure all fixings.
7. Test all lamp functions (tail, brake, indicator, reverse if applicable) before reassembling trim.
8. Reconnect the battery and ensure all fasteners and seals are correctly refitted to maintain water resistance.

Use dielectric grease on terminals to improve contact longevity and help prevent corrosion. Replace damaged seals or gaskets to restore watertight integrity.

Why Replace This Part

Replacing the bulb holder is a cost-effective repair when the lamp unit itself is intact but electrical contacts or connector assemblies have failed. It restores reliable lighting and road safety without the expense of a full lamp replacement.
