Purpose and Function of the Component

The presented element is a wiring harness with a plug socket connector dedicated to the right front headlight in a Mercedes W204. It is responsible for:

• transferring power to the bulbs and modules in the headlight,
• ensuring stable electrical contact under conditions of vibration and temperature changes,
• reducing the risk of contact overheating thanks to the precisely fitted socket design.

Thanks to its factory-matched design for Mercedes installations, the connection system remains consistent with the vehicle's original electrical architecture, facilitating diagnostics and subsequent servicing.

Construction and Fit for Mercedes W204

The wiring harness with connector has been specifically designed for the front right headlight, taking into account the lamp's geometry and the routing of wires in the front compartment. Its placement on the vehicle, designated as front – right side, minimizes the risk of errors during part selection and installation.

The plug socket solution enables:

• direct connection to the factory headlight without any installation modifications,
• preservation of the original pin layout and wire color coding,
• easy disassembly for future service work.

Benefits of Using an Original Headlight Connector

Using an original connector with a wiring harness in the lighting system brings tangible operational benefits:

• Compatibility with Mercedes Installation – no need for soldering, creating adapters, or interfering with the factory wiring harness.
• Stable headlight operation – proper power supply to low beam, high beam, and any additional lamp functions.
• Reduced errors in onboard systems – correct resistances and contacts minimize the risk of bulb or circuit failure messages.
• Serviceability – in case of future repairs, it is easy to identify and replace a single component instead of the entire lamp.

Condition and Service Application

The component is offered as a used original component, allowing for the preservation of factory manufacturing standards at a lower cost than a new wiring harness. This type of part is particularly suitable for:

• repairs after mechanical damage to the headlight,
• problems with intermittent power supply to the lights on the right side,
• restoration of the lighting system after corrosion or contact overheating.
