Purpose and vehicle placement

The presented lamp belongs to the Rear lights and brake lights group and is intended for installation in the rear right part of the vehicle, directly on the tailgate. The design was developed specifically for the body geometry of the Mercedes ML W166, which allows for:

• proper alignment with the tailgate edges,
• stable mounting at factory points,
• preservation of the original light line of the rear of the car.

Such a fit translates into seamless integration with the other rear lamps and the maintenance of the vehicle's factory aesthetics.

Technical and functional characteristics

The tailgate lamp in the Mercedes ML W166 is responsible for supplementing the main rear lighting assembly, working in conjunction with other system components. Its task is to correctly reproduce the factory light distribution, which is important for both safety and regulatory compliance. The design intended for the rear – right side ensures:

• correct positioning of light points relative to the vehicle axis,
• compatibility with the factory electrical installation,
• consistency of light color and intensity with the other lamps.

By maintaining the original geometry and mounting points, the component can be installed as a direct replacement for a damaged lamp, without the need for bodywork or electrical modifications.

Condition, origin, and benefits of use

The offered lamp is a used component, which allows for combining reasonable cost with the preservation of the manufacturer's original specifications. In practice, this means:

• factory fit for the body and electrical system,
• preservation of the original styling of the rear of the vehicle,
• the possibility of an economical repair after a collision or mechanical damage.

Using an original tailgate rear lamp helps maintain the visual consistency of the entire lighting set, which is important both from the point of view of safety and the vehicle's value on the secondary market.

Practical application and installation

The rear tailgate lamp on the right side is particularly useful in situations where there has been:

• mechanical damage to the tailgate or body corner,
• cracking of the lens and loss of tightness,
• malfunction of parts of the lighting system on the right rear side of the vehicle.

Thanks to the preservation of the factory design, installation comes down to removing the damaged component and installing the functional lamp in the existing mounting points. This solution allows for the quick restoration of full rear lighting functionality without interfering with the body structure.
