A2129005424 LED Headlight ILS Control Module – Mercedes-Benz & Infiniti Q30 QX30

HIDS-DIRECT | REPLACEMENT LIGHTING CONTROL

A2129005424 LED Headlight ILS Control Module

For matching Mercedes-Benz factory LED headlamps

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

Coding, programming or initialisation may be required for the vehicle and headlamp system. Infiniti applications require the correct Infiniti configuration. For QX30, this module is for the matching high-version headlamp application. Contact us before ordering for Infiniti to confirm the original module reference and required programming.

The matching high-version QX30 configuration uses the related references A2129005424 + A2228700789. This listing supplies one A2129005424 control module. The A2228700789 LED headlamp power module is a separate unit with a different role; the two are not interchangeable.

Replace the module identified as faulty rather than assuming both need replacement. A2129005324, associated with the QX30 low-version configuration, is also a different module and is not a replacement reference for this product.

These are identification and module-family references retained from the application information. They are not a guarantee that every hardware, software or vehicle version is interchangeable. Confirm the exact original reference and required configuration before ordering, particularly where the original label differs from A2129005424.

A faulty headlamp control unit may be associated with warnings such as “Intelligent Light System (ILS) inoperative”, left or right low-beam malfunction, or an LED lighting fault.

These warnings are not a diagnosis of this module. Check fault codes, wiring, connectors, the LED light source, other headlamp modules and coding before replacing parts. A failed low beam does not by itself establish that A2129005424 is the faulty component.

Professional diagnosis and fitting are recommended. Follow the vehicle manufacturer’s electrical isolation and headlamp removal procedures. Inspect connectors and the headlamp for moisture or corrosion, and rectify any water ingress before fitting.

The module may require vehicle-specific coding, programming, initialisation or adaptation. Infiniti applications need the correct Infiniti configuration. Use suitable diagnostic equipment and verify the relevant headlamp functions and adjustment after installation.

Complete headlamp, bulbs, LED light source, A2228700789 power module, other control units, coding service and fitting accessories are not included. This is not a genuine Continental, Mercedes-Benz or Infiniti product. Manufacturer names and OE numbers are used for identification only.

It is an LED headlamp control unit used in matching factory LED headlamp systems. Depending on the headlamp specification, it manages LED lighting functions such as daytime running lights and indicators and works with other headlamp electronics. It is not a complete headlamp, LED bulb or universal voltage converter.

Applications include selected E-Class W212/S212/C207/A207, CLS C218/X218, B-Class W246/W242, GLE W166/C292, GLS X166 and V-Class/Vito W447 headlamps. Match the original module reference, connectors and headlamp equipment. A vehicle model, year, engine or trim name alone does not confirm fitment.

This replacement can be coded for the matching Infiniti QX30 high-version headlamp application. Confirm that the original control module is A2129005424 and contact HIDS-DIRECT before ordering to confirm the correct Infiniti configuration. It is not a substitute for the A2129005324 low-version module.

Original A2129005424 modules are documented on Infiniti Q30 vehicles. Fitment is conditional on the original module reference, headlamp specification and correct replacement configuration. Contact HIDS-DIRECT before ordering to confirm programming and compatibility for your particular Q30.

Coding, programming or initialisation may be required depending on the vehicle and headlamp specification. Infiniti applications require the correct Infiniti programming. Confirm the required configuration before ordering and use an installer with suitable diagnostic equipment. Do not assume this is a coding-free plug-and-play replacement.

No. A2228700789 is a separate headlamp power module used alongside the related A2129005424 control module in the matching QX30 high-version configuration. They have different roles and are not interchangeable. This listing supplies one A2129005424 replacement only.

Yes, where the original part number, connectors and headlamp specification match and the module is correctly configured for the vehicle. It can be used on the front left or front right headlamp. One module is supplied per order.

A faulty module may cause headlamp warnings, but these messages do not identify this module as the cause on their own. Wiring faults, moisture, a failed light source, another headlamp module or incorrect coding can produce similar symptoms. Diagnose the fault before replacing parts.

This is a brand-new aftermarket replacement, not a genuine Continental, Mercedes-Benz or Infiniti part. It is supplied with a 1-year warranty. Manufacturer names and original part numbers are used for application identification only.
