Description
Bulb holder for the right rear lamp for first-series Citroën C1 and Peugeot 107. Functionality of the bulbs themselves is not guaranteed.
Replacement bulb socket designed for the right rear lamp cluster of early Citroën C1 and Peugeot 107 models. This reliable mechanical component secures the bulbs in the lamp housing and provides the electrical contacts necessary for turn, brake and tail light function. Frequently searched under part number 634681 and OEM references 81550-0H060, 6351X8, 6351X6, this part is a common maintenance item for older C1/107 vehicles and for collision repairs.
Fitment And Intended Use
Fits First-Series Vehicles:
- Citroën C1 (First Series)
- Peugeot 107 (First Series)
Use For: Right Rear Lamp Cluster Bulb Retention And Electrical Connection. Ideal For Mechanics And Do-It-Yourself Repairers Performing Lamp Unit Service Or Bodywork.
How The Part Functions
The holder secures individual bulbs inside the rear lamp assembly and provides the mating electrical contacts. It ensures correct bulb alignment, reliable contact under vibration, and isolates the socket from the lamp housing. While the holder supplies the connector interface, the actual bulb life depends on the bulb type and electrical system condition.
Replacement Procedure
- Open The Boot And Remove Any Interior Trim Panels To Access The Rear Lamp Cluster.
- Unscrew Or Unclip The Lamp Assembly From The Body (Depending On Model Variation) And Withdraw The Cluster Slightly.
- Disconnect The Wiring Connector From The Bulb Holder.
- Release The Old Holder From The Lamp Housing (Twist-Lock Or Clip Design) And Remove The Bulbs If Necessary.
- Fit The New Holder, Ensure Bulbs Are Correctly Seated, Reconnect The Wiring And Test Lights Before Reassembling The Trim.
- Tighten Fasteners To Manufacturer Spec And Check Lamp Sealing To Prevent Water Ingress.
Installation Recommendations
- Disconnect The Negative Battery Terminal When Working With Electrical Components To Avoid Short Circuits.
- Inspect Bulb Contacts And Wiring For Corrosion Or Damage; Replace Damaged Bulbs Or Connectors.
- Apply A Small Amount Of Dielectric Grease On Contacts To Reduce Corrosion And Improve Longevity.
- Ensure The Lamp Gasket And Lens Are Properly Sealed After Reassembly To Prevent Moisture Entry.
- Test All Rear Light Functions (Tail, Brake, Turn, Reverse Where Applicable) After Installation.
Why This Part Most Commonly Fails
Typical failure modes include Corrosion Of Electrical Contacts Due To Moisture, Plastic Fatigue Or Cracking From Age And Heat Cycles, Mechanical Damage From Impacts Or Rough Handling During Bulb Replacement, And Poor Contact Caused By Loose Or Worn Terminals. Water Ingress Through A Cracked Lens Or Worn Seal Accelerates Corrosion And Causes Intermittent Or Complete Loss Of Function.
Expected Service Life
Service Life Varies With Vehicle Age, Environment And Maintenance. On Older Vehicles Or Those Exposed To Road Salt And Moisture, Replacement Is Often Required as Part Of Routine Bodywork Or After Lamp Unit Damage. Regular Inspection During Lamp Or Body Repairs Helps Prevent Sudden Failures.
