Installation characteristics

The lamp is prepared for installation in the factory location on the left side of the tailgate. Properly designed mounting points and an electrical connector allow for installation in the standard vehicle configuration, without the need for additional adapters. This solution reduces the time spent working on the vehicle and minimizes the risk of installation errors.

Due to its classification in the Rear lights and brake lights category, the component works with the lighting system responsible for braking, position, and other functions provided for this specific body model.

Product condition and service application

The offered lamp is a used component, which makes it an attractive option for post-accident repairs, replacing a damaged lens, or restoring the vehicle to its factory specification. Choosing an original used component allows for cost savings compared to new replacements, while maintaining the correct fit for the specific body version.

This type of solution is particularly effective in situations where the priority is a quick and technically correct replacement of a lighting component without interfering with the vehicle's structure.
