Part Description
This OEM left-hand headlamp assembly was removed from a 2008 Mercedes-Benz S-Class S550 donor vehicle. The unit features advanced bi-xenon HID lighting technology with integrated night vision capability, representing Mercedes-Benz’s premium lighting system for the W221 platform. This headlamp has been professionally inspected and is currently on our shelf, ready to ship.
Mercedes-Benz S-Class headlamp assemblies commonly require replacement due to accident damage, moisture intrusion causing electrical failures, or HID ballast malfunctions. The bi-xenon system provides superior illumination compared to standard halogen units, while the night vision integration requires precise OEM specifications for proper functionality. Stone chips, UV degradation of the lens, and internal component failures are typical reasons owners seek replacement units.

Frequently Asked Questions
Will this headlamp work with my 2008 Mercedes S550 without night vision?
This unit includes night vision capability, so you’ll need to verify your vehicle’s wiring harness compatibility. The basic HID function will work, but night vision features require proper vehicle equipment and coding.
Does this headlamp assembly include the HID ballast and bulbs?
The assembly includes the integrated bi-xenon projectors and mounting points. HID ballasts and bulbs may need separate verification – contact us to confirm what components are included with this specific unit.
How do I know if this fits my Mercedes S-Class year?
This fits 2007-2009 W221 S-Class models with bi-xenon HID systems. Use interchange number 50584A to cross-reference, or provide your VIN for exact fitment verification.
What’s the difference between bi-xenon and regular xenon headlamps?
Bi-xenon systems use HID technology for both low and high beams with a mechanical shutter, while regular xenon only uses HID for low beam. This provides better high-beam performance and more consistent light output.
Can I install this headlamp myself?
Installation requires removing the front bumper cover and accessing mounting bolts behind the headlamp. Professional installation is recommended due to HID electrical connections and proper headlamp aiming requirements.
Why choose a used OEM headlamp over aftermarket?
OEM units maintain original fit, finish, and performance specifications including proper HID projector alignment and night vision integration. Aftermarket units often lack the precise engineering and premium materials of genuine Mercedes-Benz components.
