9618206639 head lamp is a left-hand black headlight assembly specified for MERCEDES-BENZ ACTROS MP4 vehicles in the 2011–2018 model range. This new-type design uses dark internal styling and a compact housing to give the front of the truck a more modern appearance while maintaining compatibility with the original MP4 bumper and cab lines. It is aimed at fleets and workshops that need a direct-fit replacement lamp after collision damage, stone impact or age-related lens wear.

The 9618206639 head lamp combines a glass lens section with a durable plastic rear body so that optical clarity, impact resistance and overall weight are well balanced for heavy-duty applications. When fitted with the correct bulbs and correctly aimed, the reflector and lens geometry provide a controlled dipped-beam cut-off and strong main-beam reach, supporting safe night-time driving on highways, regional routes and depot access roads. The black internal appearance of this head lamp pairs visually with the right-hand 9618206739 unit to create a matched “black type” lighting set for ACTROS MP4 trucks.

Mounting studs, alignment tabs and connector locations on the 9618206639 head lamp follow MERCEDES-BENZ ACTROS MP4 front-end engineering so the lamp seats naturally in the left-hand bumper aperture without stressing surrounding panels or trim. Supplied without bulbs, it allows fleets and workshops to standardise on their preferred bulb suppliers and technologies while using a single housing reference across many vehicles.

For operators refreshing the look of older MERCEDES-BENZ ACTROS MP4 vehicles, the 9618206639 head lamp offers an effective way to upgrade both styling and lighting performance, especially when installed together with matching right-side lamps, mirrors, bumpers and other truck body parts from the same supplier range.
