Purpose and fitment

The presented lamp is dedicated to the Mercedes ML W166 generation model and is mounted on the front right side of the vehicle. The headlight construction is compatible with factory mounting points, which facilitates installation and allows for maintaining the correct beam geometry. Thanks to the preservation of the original housing and lens form, the headlight harmoniously fits into the body line, maintaining a consistent look for the front of the car.

Function in the lighting system

The headlight is responsible for generating the main light beam for low and high beams (depending on the vehicle configuration), as well as for the vehicle's visibility to other road users. Properly selected internal optics and correct lamp adjustment affect:

• clear illumination of the lane in front of the vehicle,
• reduction of glare for oncoming drivers,
• compliance with technical inspection requirements.

Using an original headlight in place of a damaged element allows you to maintain factory lighting parameters, which is important for both safety and comfort when driving at night.

Product characteristics and condition

The offered headlight is a used OEM Mercedes component, sourced from dismantling. This type of part is a good solution for post-accident repairs or replacing a damaged lamp when you want to maintain original build quality and compatibility with the vehicle's electrical installation. A used headlight allows you to reduce service costs while maintaining the factory standard of fitment.

The placement on the vehicle has been clearly defined as front – right side, which minimizes the risk of error when selecting the component. Combined with the correct OEM part number and available interchangeable numbers (visible in the specification), this facilitates verification of compatibility with the specific equipment version of your ML W166.

Professional selection and application

To ensure that the headlight will be fully compatible with your vehicle, it is worth comparing the markings with factory data and paying attention to the mounting side and model generation. Proper selection of an element from the Front lights category translates into trouble-free installation, no need for modifications, and correct operation of all lighting functions.
