9618200859 head lamp is a left-side full LED headlight designed for MERCEDES-BENZ ACTROS MP4 and MP5 Euro 6 trucks. It replaces the front left lamp unit and delivers a modern LED light signature with improved visibility, low power consumption and a sharp beam pattern tailored to long-haul and regional applications. Multiple catalogues and fitment guides list this part against ACTROS MP4/MP5 with installation on the front left position.

The 9618200859 head lamp combines a plastic outer body with internal iron and aluminum structures to support the LED modules, heat sinks and mounting points. This construction provides a balance of strength, weight and heat management appropriate for heavy commercial vehicles. Full LED technology in the dipped beam, main beam and position functions helps deliver a crisp white output while reducing current draw and maintenance frequency compared with traditional halogen systems, especially on multi-shift ACTROS vehicles that spend long hours running at night.

All mounting points, guides and connector locations on the 9618200859 head lamp follow the MERCEDES-BENZ ACTROS MP4/MP5 front bumper design so the lamp seats correctly in the left housing without stressing the cab structure or trim pieces. In OE-style references it is often paired with the prefix variant A9618200859, giving workshops and parts departments a familiar alternate number while they continue to manage a single physical lamp in stock. The product is typically supplied in a paper box with plastic film wrapping for protection, ready for shipment by sea, air or road to fleet depots and distributors worldwide.

For ACTROS operators upgrading from earlier lamps or repairing collision damage, the 9618200859 head lamp offers a visually clean, factory-style solution that restores both lighting performance and the modern MP4/MP5 front-end appearance. Its LED construction, heavy-duty materials and compatibility across multiple model years make it a practical, long-term choice for truck fleets that need reliable lighting in demanding conditions.

• Use the 9618200859 head lamp as the primary left full LED reference for MERCEDES-BENZ ACTROS MP4/MP5 fleets, consolidating prefix variant A9618200859 and other catalogue references into a single stocking code for warehouse and online systems.
• Take advantage of carton and product dimensions that follow the actual lamp reference to optimise pallet loading and container utilisation when shipping 9618200859 head lamp units from China or European distribution hubs to international customers.
• Support multiple sales channels by offering neutral, colour or customer-branded packaging, while keeping the 9618200859 head lamp number visible on labels for easy cross-referencing with MERCEDES and truck-parts catalogues.
• Combine orders of 9618200859 head lamp with matching right-hand LED headlamps and other body parts such as mirrors, bumpers and mudguards to create complete front-end repair or upgrade kits for ACTROS MP4/MP5 fleets.
• Plan bulk purchasing around standard delivery windows (for example 5–15 working days from some suppliers) and integrate the 9618200859 head lamp into fleet maintenance programmes that prioritise LED lighting and reduced downtime.

• Park the MERCEDES-BENZ ACTROS MP4/MP5 on level ground, apply the parking brake and isolate the battery according to workshop procedures before replacing the 9618200859 head lamp or disconnecting any LED control modules.
• Remove the grille and left-hand bumper or trim panels as needed to reach the lamp fasteners, supporting the old headlamp while you undo screws so cab panels and painted edges are not damaged.
• Pull the existing lamp forwards and disconnect the main wiring connector, checking terminals, seals and harness routing for corrosion, overheating or abrasion before installing the new 9618200859 head lamp.
• Position the replacement lamp in the left-hand bumper aperture so that guide pins, studs and locating tabs line up with MERCEDES-BENZ mounting points, then tighten the fixings evenly to avoid distorting the LED housing or changing the beam angle.
• Reconnect the wiring, restore battery power and test dipped beam, main beam, position lights and any LED signature or indicator functions; finally, place the 9618200859 head lamp on a beam tester to set the cut-off, height and lateral aim in line with local road-lighting regulations.

• Primary OE reference: 9618200859 – full LED left headlamp for MERCEDES-BENZ ACTROS MP4/MP5 trucks.
