Headlight Left - Hella 1LL-011-284-531

You must verify the specific fitment for your exact vehicle model and year. While designed for the W447 chassis, it is essential to cross-reference part numbers and specifications with your vehicle's requirements or consult a professional.

The product description often indicates if bulbs are included. If not specified, assume bulbs (PY21W, H7, H15) must be purchased separately. Check the product details or contact the supplier for confirmation.

While minor repairs might be DIY-friendly, headlight replacement on modern vehicles like the V-Class often involves bumper removal and complex electrical connections. Professional installation is recommended for optimal results and safety.

This is the headlight for the left side of the vehicle (driver's side in left-hand traffic countries). The right-side headlight (OS Offside) is a separate part, often indicated by a different part number (e.g., 1LL 011 284-541).

This assembly includes a motor for automatic headlamp levelling. Manual adjustment points may also be present, but refer to your Mercedes-Benz V-Class owner's manual for specific instructions on operation and any necessary manual adjustments.

This refers to the aesthetic appearance of the headlight housing itself, specifically the colour and finish of the internal trim or bezel, which is typically grey on this model.

This is an original equipment (OE) quality part manufactured by Hella, a supplier to Mercedes-Benz. While not branded with the Mercedes-Benz logo, it meets the same quality and performance standards as an OEM part.

Check the bulb seating and ensure it is correctly installed. Verify electrical connections to the headlight assembly are secure. Inspect fuses related to the headlight circuit and replace if blown. If the issue persists, the bulb or headlight assembly may be faulty.

Use the vehicle's headlamp levelling adjustment mechanism. If the levelling motor appears to be malfunctioning, professional diagnosis and potential replacement of the motor or headlight assembly may be required.

Check that all seals and covers are properly fitted. If persistent condensation occurs, the headlight assembly may have a seal failure and require replacement to prevent further damage to bulbs and electrical components.

Verify the specific bulb type (e.g., PY21W for indicator) is correctly installed and functional. Check the corresponding fuse and electrical connections for that specific light function.
