Purpose and function in the vehicle

The described tailgate rear lamp is dedicated to the W166 series body and is mounted on the rear of the vehicle on the right side.

Thanks to its factory design, it ensures consistent light distribution, clear signaling for other road users, and maintains the original light line characteristic of Mercedes models.

Construction and fitment for Mercedes W166

The lamp has been designed as an element of the rear lighting system, with geometry matched to the contours of the tailgate in the Mercedes W166. Proper edge routing, mounting points, and lens shape allow for precise fitting with the bodywork and adjacent lamps, which reduces the risk of leaks and improper seating. The use of an original design translates into stable mounting, proper sealing, and an aesthetic appearance without the need for modifications.

Characteristics of the used component

The offered tailgate rear lamp is a used component, which in practice means that it comes from vehicle dismantling and may show signs of wear typical for this class of parts. At the same time, it retains the functionality required for continued operation in the lighting system. For many Mercedes W166 users, this is a cost-effective solution that allows for the replacement of a damaged lighting module while maintaining the original manufacturing standard and compatibility with the vehicle's electrical system.

Benefits of using an original rear lamp

Using a factory tailgate rear lamp on the right side in a Mercedes W166 provides several significant benefits:

• preservation of the original light line and appearance of the rear of the vehicle,
• secure fit to the tailgate without the need for body modifications,
• consistency with other rear lighting elements,
• maintenance of correct light signaling in accordance with the manufacturer's specifications.

For users who value factory Mercedes solutions, this is a practical way to restore full lighting functionality after a collision, mechanical damage, or lamp failure.
