Purpose and vehicle placement

The described rear lamp is intended for installation in the rear zone, on the right side of the vehicle, within the body side panel. This placement guarantees proper visibility of light signals for drivers behind the vehicle and maintains the factory lighting geometry.

• increases the clarity of light signals for other road users,
• reduces the risk of rear-end collisions,
• maintains the vehicle's compliance with lighting homologation requirements.

Replacing a damaged or leaking lamp with an original component allows for the restoration of full lighting system functionality without compromising safety.

Characteristics of the original Mercedes component

The offered rear lamp comes from the Mercedes brand, which means it maintains factory standards of quality, fitment, and compatibility with the body and electrical system. Using an OEM element is a solution that:

• maintains a consistent appearance of the vehicle's rear section with the other lamps,
• ensures proper light diffusion and intensity in accordance with the manufacturer's design,
• reduces the risk of vehicle diagnostic system errors resulting from incorrect electrical loads.

The used condition allows for an economical replacement while maintaining the original construction and operating parameters, which is particularly important in the case of modern lighting systems.

Benefits of use in the Mercedes W177

Using this rear right lamp in a Mercedes W177 brings a number of practical benefits:

• Factory fitment – compatibility of shape and mounts with the body minimizes installation time.
• Consistent aesthetics – preservation of the original styling line of the vehicle's rear section.
• Correct cooperation with electronics – the lamp is designed to work with the vehicle systems of this generation.

Thanks to this, the product is suitable for both post-accident repairs and the replacement of a worn-out component.
