Purpose and function in the lighting system

The presented bulb holder is a component mounted in the rear lamp on the left side, responsible for securely holding the bulbs and their electrical connection to the vehicle's wiring. The design, tailored to the specific W169 body generation, allows for maintaining the factory layout of light points, such as position lights, brake lights, or turn signals, in accordance with the manufacturer's design.

Thanks to the use of an original solution from the Lamps and LED lights group, compatibility with the factory wiring harness and the vehicle's electrical parameters is maintained. Proper contact routing reduces the risk of overheating, flickering lights, or intermittent power supply, which is important for both safety and the absence of errors in lighting control systems.

Construction and fitment for Mercedes W169

The socket has been designed as a component dedicated to the specific tail lamp in the W169 generation A-Class Mercedes, which translates into proper fitment with the lamp housing and stable bulb positioning. The layout of the sockets and contacts corresponds to the factory design, so installation does not require any modifications to the wiring or the use of additional adapters.

The properly shaped socket body facilitates installation in the lamp and subsequent maintenance, such as bulb replacement. The applied design solutions support even distribution of thermal and mechanical loads, which promotes stable operation of the lighting system in daily use.

Benefits of using an original socket

Choosing an original bulb holder for the tail lamp in a Mercedes W169 allows you to maintain consistency with the factory electrical system design.
