Peugeot Expert (3rd generation): Replacing the Low/High Beam Bulb in the Headlight
This applies to headlights with halogen bulbs. The bulb is replaced from the engine compartment through the rear cover of the headlight. If the vehicle has LED or Full LED headlights, there is no separate bulb. LED modules are replaced together with the headlight assembly, and this work is done at a repair shop. Replace bulbs in pairs if both have already seen significant service.
Part
- 🔩 Halogen bulb of the correct type with the same base as the original. For the low beam, headlights of this type usually use an H7 12 V 55 W bulb. The high beam bulb type depends on the headlight trim. It is marked on the base of the old bulb and listed in the owner's manual

Step by step
10 steps- Turn off the engine, switch off the headlights and the ignition, and wait for the bulb to cool down. A hot halogen bulb can burn you and breaks easily.
- Open the hood and locate the rear of the relevant headlight. Access to the low beam bulb may be blocked by an air duct, the air filter housing, a reservoir, or a plastic cover. If it gets in the way, remove it by releasing the clips or removing the fasteners.
- Remove the protective rubber or plastic cap (cover) from the rear of the headlight. It is held on by a bayonet twist or by clips. Note how it is positioned.
- Disconnect the power connector from the bulb base. Press the locking tab and pull on the connector housing, not on the wires.
- Release the bulb from its retainer. This is usually a spring clip: press it down and swing it aside. On some bulbs the base is held by a bayonet, in which case turn it a small angle counterclockwise. Then carefully pull the bulb straight out along its axis, without tilting it.
- Compare the new bulb with the old one: the type, wattage, and position of the base tabs must match.
- Handle the new bulb only by the base, wearing gloves. There must be no fingerprints on the glass: oil causes local overheating and quick bulb failure. If you touched the glass, wipe it with a clean cloth and alcohol.
- Insert the bulb into the socket so the base tabs fit into the slots. Secure it with the clip or by twisting, then plug in the connector until it clicks.
- Turn on the low and high beams and check that they work while the cap is still off. Then press the cap firmly back into place. It must seat all the way around, otherwise moisture will get into the headlight and it will fog up.
- Reinstall the engine compartment parts you removed. Check the beam aim against a wall or garage door. The bulb seats exactly in its socket, so the aim usually isn't disturbed. However, if the beam pattern has shifted, adjust the headlights.
Common mistakes and warnings
- If the bulb doesn't light after replacement, check the fuse and the contact in the connector. Do not install bulbs of higher wattage than specified. This will overheat the connector and melt the headlight. If the vehicle has xenon or LED headlights, do not try to replace the bulb yourself: xenon systems carry high voltage, and LED modules are replaced as an assembly at a repair shop. The exact location and the order for removing the air duct depend on the engine version and trim, so work according to the access you actually have in your engine compartment and do not apply excessive force to the plastic clips.
