Purpose and function in the lighting system

The presented socket holder with wiring is a component of the Rear lights and brake lights group, dedicated to the Mercedes W176 body. It is mounted at the rear of the vehicle, on the left side, where it is responsible for the correct seating of the bulbs and their electrical connection to the car's wiring. This makes it possible to maintain the proper light intensity and clear braking and position signaling for other road users.

Construction and mounting compatibility

The holder is an integrated assembly of bulb sockets with a section of the wiring harness, prepared for use with the rear lamp on the left side. The design is matched to the geometry of the lamp in the Mercedes W176, which facilitates installation in the housing and connection to the factory connector. The plug-in solution reduces the risk of installation errors and allows for efficient replacement of a damaged component without the need to modify the electrical system.

Benefits of using an original Mercedes component

Using an original bulb holder with wiring in a Mercedes W176 allows you to maintain consistent electrical parameters and proper cooperation with the vehicle's diagnostic systems. Properly selected wire cross-sections, correct contacts, and factory connectors minimize the risk of voltage drops, flickering lights, or lighting error messages. This solution is particularly beneficial for post-collision repairs or when replacing a damaged lamp, where stable lighting system operation and adherence to manufacturer standards are required.

Condition, service application, and part selection

The item comes from dismantling, which makes it an attractive cost-effective alternative to new components while maintaining the original manufacturer's specifications. It works well both for local lighting system repairs and for comprehensive reconstruction of the rear of the vehicle after mechanical damage. Thanks to the preservation of factory geometry and connectors, installation is predictable, and the risk of incompatibility with the rear lamp on the left side is limited.
