Application
Fits the right rear lamp assembly of first-generation Citroën C1 and Peugeot 107. Intended as a direct replacement socket for the rear lamp cluster on these models; check the lamp assembly shape and connector position to confirm fitment.
Function
The bulb holder secures rear light bulbs in the lamp cluster and provides the electrical connections (positive feed and ground) via the vehicle wiring. It maintains bulb position and contact under vibration and heat cycles, and helps seal the electrical contacts from moisture when correctly installed.
Common Failure Reasons
- Age and Heat Cycling: Plastic and contacts become brittle with time and repeated heating from the bulbs.
- Corrosion and Moisture Ingress: Water penetration leads to oxidized contacts and intermittent connection.
- Mechanical Damage: Rough removal or impact can crack the holder or damage retaining tabs.
- Wiring Wear: Chafed or broken wires near the pigtail cause open circuits or shorts.
Replacement Procedure
Basic steps for replacing the right rear bulb holder on Citroën C1 / Peugeot 107:
- Park the vehicle on a level surface and switch off all lights.
- Disconnect the negative battery terminal to avoid short circuits while working on the lighting circuit.
- Open the boot and remove any interior trim panels or covers that block access to the rear lamp cluster.
- Unscrew or unclip the tail lamp assembly fasteners and gently pull the lamp unit out far enough to access the bulb holder.
- Unplug the wiring connector from the old bulb holder and twist or unclip the holder to release the bulb(s) according to the lamp design.
- Install the new bulb holder, connect the pigtail wiring, test all lamp functions (brake, tail, indicator, reverse if applicable) before reassembling.
- Reinstall the lamp assembly and trim, torque fasteners to manufacturer values, and reconnect the battery.
Installation Advice
- Use dielectric grease on electrical contacts to reduce corrosion and improve long-term reliability.
- Ensure gaskets and seals are intact to prevent moisture ingress into the lamp housing.
- Do not overtighten plastic fasteners; replace any damaged clips to ensure proper fit.
- Verify correct bulb types and polarity before final assembly.
Why This Part Often Fails
Rear lamp bulb holders typically fail due to long-term exposure to heat from the bulbs, combined with moisture and vibration. Over time the plastic can crack and contacts can corrode, causing intermittent or complete loss of lighting. Improper installation or repeated removal can also damage retaining features and wiring.
Note
The sale includes the bulb holder with a short section of wiring. Functionality of any bulbs is not guaranteed; bulbs may need to be tested or replaced separately.
