Used rear fog lamp specifically for the Citroën C4 Coupe (3-door, first generation). Supplied with the bulb and a short section of wiring for a direct fit — a practical replacement for workshops and home mechanics. The assembly restores rear fog illumination to OEM standard, improving safety in poor visibility and ensuring correct fitment under original part numbers.

Description And Function

The rear fog light increases vehicle visibility in fog, heavy rain or snow by providing a high-intensity red beam at the rear of the car. This left-side unit is a complete housing with lens, bulb holder and attached wiring piece, ready to be installed in place of a damaged or non-functioning lamp. It is an OEM-fit component with mounting points designed for the Citroën C4 Coupe bodywork.

How To Replace

• Prepare Tools: Torx/Phillips screwdrivers, trim removal tools, protective gloves.
• Safety First: Disconnect the negative battery terminal before starting work.
• Access: Depending on vehicle trim, remove the trunk interior trim or access panel behind the lamp to reach the mounting screws and connector.
• Removal: Unscrew the lamp retaining bolts, carefully unplug the bulb connector and remove the old unit from the bumper aperture.
• Fitment: Connect the supplied wiring piece to the vehicle harness, insert the lamp into the aperture, and secure with the original fasteners.
• Test: Reconnect the battery, verify operation of the fog lamp, and check alignment. Replace interior panels.

Installation Recommendations

• Always Disconnect The Battery Before Removal And Installation.
• Use Dielectric Grease On Electrical Connectors To Prevent Corrosion And Improve Contact.
• Avoid Touching The Glass Of Halogen Bulbs With Bare Hands; Contaminants Shorten Bulb Life.
• Check Mounting Points And Seals For Damage; Replace Any Broken Clips To Ensure Proper Sealing Against Moisture.
• After Installation, Verify Light Operation And Beam Position To Comply With Road Safety Regulations.

Why This Part Fails Most Often

• Moisture Ingress: Broken seals or cracked lenses allow water to enter, causing corrosion and electrical faults.
• Impact Damage: Rear collisions or bumper impacts often physically damage the housing or mounting tabs.
• Bulb Failure: Bulbs have a finite life and will burn out; vibration and heat cycles reduce lifespan.
• Connector Corrosion Or Wiring Damage: Salt, dirt and mechanical wear can degrade the connector or wiring, causing intermittent or permanent failure.
