Magneti Marelli Headlight Control Module

Magneti Marelli Headlight Control Modules: OEM Expertise in Every Unit

When a headlight control module fails, the consequences go beyond a dim beam — flickering HID arcs, non-responsive adaptive lighting, and diagnostic trouble codes can all trace back to a single electronic unit tucked inside the headlamp assembly. Magneti Marelli, operating its lighting division under the AL (Automotive Lighting) banner, is one of the few suppliers that designs and manufactures these modules at the OEM level, meaning the replacement part in the box is built to the same specification as what left the factory floor.

Headlight control modules serve as the electronic brain of advanced lighting systems — regulating voltage and current to High Intensity Discharge (HID) xenon burners and LED arrays, managing adaptive curve-light functions, and communicating with the vehicle's CAN bus. Because these modules are embedded in complex lighting ecosystems, fit and calibration tolerances are extremely tight. An off-spec module can cause persistent fault codes, reduced beam output, or complete headlamp failure.

Why Magneti Marelli Stands Apart in This Category

Magneti Marelli's authority in headlight control modules flows directly from its roots as an OEM lighting supplier. AL-Automotive Lighting, a Magneti Marelli subsidiary, designs and integrates advanced external lighting solutions for major automakers, which means the control modules in their aftermarket catalog are not reverse-engineered approximations — they are the same engineering lineage as the original parts. This heritage is particularly relevant for European marques: Magneti Marelli HID and LED control modules are catalogued for vehicles including Mercedes-Benz C-Class, CLA, GLA, and S-Class models, as well as Audi A6, A7, S7, and RS7 platforms.

The product lineup spans both xenon and LED architectures. The LRB880 and LRB200 are HID headlight control modules built for Mercedes-Benz applications, regulating power delivery to xenon low-beam and curve-light systems. The LRA910 targets Audi HID systems, and the LRA650 addresses xenon voltage-converter duties on Mercedes-Benz S-Class platforms. For newer vehicles, Magneti Marelli also catalogs LED headlight control modules (such as part 2189009203) to support the increasingly common LED headlamp systems found on late-model European cars and SUVs.

What to Know Before You Buy

Because luxury and European vehicles frequently offer multiple lighting packages on the same model year, VIN verification is strongly recommended before ordering any headlight control module. A C-Class or S-Class, for example, may have been built with standard halogen, bi-xenon, or full-LED headlamps depending on the original equipment specification — and each requires a distinctly different control module. Magneti Marelli's OEM-level part numbering system makes cross-referencing straightforward for technicians familiar with OE part numbers.

• HID/Xenon modules (LRB880, LRB200, LRA910, LRA650): Regulate ballast voltage for xenon arc lamps; address fault codes P2300–P2303 and headlight flickering symptoms.
• LED control modules: Manage multi-channel current to LED headlamp arrays and adaptive lighting functions on newer platforms.
• OE-match fitment: Parts are engineered to OEM specifications, eliminating the calibration issues common with generic aftermarket alternatives.
• European vehicle focus: Coverage spans Mercedes-Benz, Audi, and BMW headlamp systems — platforms where factory lighting electronics are among the most complex in the industry.

For technicians and enthusiasts who refuse to compromise on lighting safety and reliability, Magneti Marelli's headlight control modules represent the closest available alternative to sourcing direct from the vehicle manufacturer's parts counter — typically at a significantly more accessible price point.
