Purpose and function of the rear lamp holder

The rear lamp holder in Mercedes W204 class models is responsible for precisely holding the light sources and correctly routing electrical signals to individual lighting functions. The component is mounted in the rear area of the vehicle on the left side, which allows for the proper operation of position lights, brake lights, turn signals, or reversing lights – in accordance with the specific lamp configuration. Thanks to its factory geometry and fitment to the body structure, the holder ensures proper positioning of the bulbs relative to the lens, which affects uniform light distribution and signal clarity for other road users. This is particularly important in daily operation, where stable operation of the rear lighting is directly related to safety.

Compatibility and fitment for Mercedes W204

The presented holder has been designed specifically for the Mercedes W204 platform, which means full compatibility with the factory mounting points and the electrical harness intended for this model. The appropriate shaping of the holder body facilitates installation in the lamp socket, minimizing the risk of stress and leaks within the lighting assembly. The original origin from the Mercedes brand translates into maintaining the parameters specified by the vehicle manufacturer, including resistance to the temperature generated by the bulbs and the stability of contact connections. This is especially important during long-term operation, where lower-quality replacements can cause circuit interruption problems or overheating of the sockets.

Technical characteristics and installation

The holder is intended for installation in the rear part of the vehicle on the left side, which in practice means it fits a specific lamp module in the W204 body. The placement on the vehicle has been clearly defined as Rear - left, making it easy to verify the component's compatibility with your lighting configuration. The arrangement of bulb sockets and electrical contacts is consistent with the factory design, which allows for the use of the existing harness without the need for modifications. For the user, this means installation in a plug-and-play format – after removing the damaged holder, you can transfer the bulbs and connect the plug, restoring full functionality to the rear lamp.

Condition of the component and benefits of using a used part

The offered rear lamp holder is a component in Used condition, which allows you to combine reasonable purchase costs with maintaining the manufacturer's original specifications. Parts of this type are frequently chosen for post-accident repairs, replacing damaged holders after socket overheating, or when dealing with unstable electrical contact issues. Using an original, used holder allows you to maintain the structural consistency of the lighting assembly while limiting the risk of poor fitment, which is typical for cheaper replacements. This is a practical solution for users who expect factory fitment and predictable lighting system performance without straining their service budget.

Part identification and reference numbers

To facilitate the selection of the correct component in service catalogs and sales systems, the product has assigned technical markings. The internal warehouse identifier in our store is SKU, while the manufacturer's documentation uses the OEM Part Number. Additionally, there are interchangeable numbers available, which help verify compatibility with other versions of this holder used within the same model platform. If you are planning a comprehensive repair or upgrade of the rear lighting zone in your Mercedes and need other elements from the same group, such as lenses, lamp modules, or additional holders, check the available parts in the Mercedes Rear lights and stop lights category.
