A2228700789 LED Headlight Power Module

Replacement LED ballast / voltage converter for compatible Mercedes-Benz headlamps

Also supports matching Infiniti QX30 high-version applications with the correct Infiniti coding. Q30 fitment requires an original-module and configuration check.

This module requires coding for the vehicle and headlamp system. Initialisation or adaptation may also be necessary. Infiniti applications require the correct Infiniti configuration. Please contact us before ordering for an Infiniti and arrange suitable diagnostic equipment and professional fitting.

The high-version QX30 headlamp configuration uses the related module references A2129005424 + A2228700789. The A2129005424 ILS headlamp control module is a separate unit with a different role; it is not an alternative part number for this power module. This listing supplies one A2228700789 replacement only. Replace the unit identified as faulty rather than assuming both modules need replacement.

The A2129005324 low-version module is also a different unit and is not interchangeable with this product. Contact us if you need help identifying the correct headlamp configuration.

Reference numbers help identify the relevant module family. Related or superseding numbers do not guarantee that every software version or vehicle configuration is interchangeable. Confirm compatibility and coding requirements against the original unit before purchasing.

Professional diagnosis and installation are recommended. Follow the vehicle manufacturer’s electrical isolation and headlamp removal procedures. Check wiring, plugs and the headlamp light source before concluding that the power module has failed.

Inspect the headlamp for moisture, corrosion and damaged seals. Rectify water ingress before installing the replacement.

Code the replacement to the vehicle and perform any required initialisation, adaptation and lighting checks using suitable diagnostic equipment. Confirm correct operation of all relevant headlamp functions after fitting.
