Rear fog light, left, for CITROËN C4 3‑door Coupe – first series. With bulb and a piece of wiring. Driver’s side.
Product Overview
Direct-fit left rear fog lamp for the Citroën C4 (3‑door Coupe, first series). This used assembly comes with the bulb installed and a short length of wiring for straightforward connection. Designed for mechanics and experienced DIYers who need a reliable replacement part that matches the original equipment fitment and mounting points.
Why Choose This Part
- OE-compatible fit for clean installation and correct alignment in the rear bumper.
- Included bulb and wiring reduce additional parts and make immediate testing possible after installation.
- Cost-effective solution for repairing damaged or non-functioning rear fog light on Citroën C4 Coupe.
Function And Common Faults
The rear fog lamp improves visibility to following traffic in poor weather conditions (fog, heavy rain, snow). The most frequent causes of failure are bulb burnout, moisture ingress causing corrosion of contacts and sockets, physical damage from minor rear impacts, and deteriorated wiring/connectors. Bulbs supplied are typically halogen and their service life depends on usage and vibration; under normal driving conditions halogen bulbs usually last several hundred hours.
Replacement Guide
Replacement is straightforward for a competent technician. Typical steps:
- Disconnect the battery before starting electrical work to avoid short circuits.
- Access the fog light from inside the trunk or through the rear bumper wheel‑arch/undertray depending on model and local assembly variations.
- Remove retaining screws or clips, pull the lamp assembly out of its housing, and unplug the connector.
- Install the new assembly, reconnect the wiring, secure mounting fasteners, and test the lamp operation before reassembling trim panels.
Note: Avoid touching the glass of a halogen bulb with bare fingers; oils can shorten bulb life.
Installation Recommendations
- Use proper trim tools to prevent damage to interior panels and bumper clips.
- Check the connector for corrosion and clean or replace corroded terminals to ensure a reliable electrical connection.
- After installation, verify correct alignment and operation of the lamp and check that the rear fog lamp switch and indicator function normally.
- If bumper removal is required, follow the vehicle manufacturer’s procedure and torque settings for fasteners.
Why This Part Fails Most Often
Most failures are caused by bulb burnout and water ingress. Condensation or leaks allow moisture to reach the bulb holder and connector, causing corrosion and poor contact. External impacts to the bumper can crack the lamp housing or misalign the assembly, and worn wiring or damaged connectors lead to intermittent operation.
