Application and vehicle function

The described left rear lamp is a component of the lighting system in the Rear lights and brake lights category, mounted on the left side of the rear bodywork. It is responsible for the vehicle's rear visibility, correct outline marking, and clear signaling of maneuvers to other road users.

Its placement in the side panel allows the lamp to work in conjunction with the other rear lights, creating a uniform optical system. Proper alignment of the lens geometry and mounting points allows for stable installation without the need for bodywork modifications.

Compatibility and fitment

The component has been designed specifically for the Mercedes ML W164 generation, which means it maintains factory body lines and proper fitment with the tailgate and bumper. The original design ensures:

• correct positioning of light points relative to other lamps,
• compatibility with the vehicle's electrical system,
• easy installation in place of the factory lamp without additional adapters.

As a result, replacing a damaged component with this lamp allows for the restoration of proper rear lighting operation without interfering with the wiring harness or bodywork.

Product characteristics and condition

The offered left rear lamp is an original Mercedes brand part, which translates into maintaining factory optical and mechanical parameters. The product is in used condition, making it a reasonable choice for users looking for a technically sound solution with a favorable price-to-quality ratio.

As a part sourced from dismantling, the lamp allows for maintaining the vehicle's stylistic consistency, especially when replacing a single lighting module. This is a practical solution for post-accident repairs, mechanical damage, or lighting system failures.

Benefits of using an original rear lamp

Using an original rear lamp on the left side of a Mercedes ML W164 provides a number of measurable benefits:

• Factory fitment – no installation issues, proper adhesion to the bodywork, and preservation of body lines.
• Stable lighting parameters – appropriate light intensity and distribution, consistent with the manufacturer's design.
• Operational safety – clear signaling of braking and vehicle presence on the road.
• Consistent aesthetics – a uniform look for the rear of the car without differences in lens shade or lamp shape.

Matching by part numbers and selecting used parts

The lamp has a dedicated OEM part number and associated interchangeable numbers, which facilitates precise verification of compatibility with a specific vehicle equipment version. When selecting a used component, it is worth comparing the markings with technical documentation or the removed lamp to ensure that the module will work with the electrical system and bodywork of the given vehicle.
