Purpose and vehicle placement

The presented rear left side panel tail light has been designed specifically for the Mercedes CLA C117 model and is intended for installation in the rear part of the vehicle on the driver's side. It is responsible for the correct reproduction of light signals in the corner area, working in conjunction with the other components of the rear light assembly. Placement in the rear zone, on the left side, is crucial for vehicle visibility during braking, lane changes, or parking maneuvers. By maintaining the original geometry and mounting points, the lamp allows for stable installation and proper alignment with the body line.

Technical and functional characteristics

• correct light distribution in the rear side part of the body,
• optical consistency with other lamps in the vehicle,
• preservation of factory homologation parameters,
• compatibility with original wiring harnesses and mounting brackets. Thanks to the use of an original solution, the lighting system maintains the operating logic intended by the manufacturer, which is important both from a safety point of view and for compliance with regulations.

Product condition and benefits of use

For many users, this is a reasonable compromise between cost and maintaining the vehicle's factory appearance. Using the original rear left side panel tail light in the CLA C117 allows you to:

• restore full lighting functionality after a collision or mechanical damage,
• maintain a consistent, aesthetic appearance of the rear body section,
