2009-2012 Audi-A4 Headlight HID Xenon Left Side OEM

Fitment and Compatibility

This is the left-side HID Xenon headlight for the Audi A4, 2009 to 2012 model years. Confirm your A4 falls within this specific production window before ordering, since headlight styling and mounting changed with the mid-cycle facelift that followed this range.

Technology and Features

HID Xenon on this generation A4 delivers a brighter, whiter beam than the standard halogen setup, using a gas-discharge bulb paired with a dedicated ballast rather than a conventional filament bulb.

Condition and What’s Included

Left-side unit only, tested for Xenon ballast function and inspected for lens clarity and housing integrity before listing.

Installation Notes

Standard bolt-in swap for this generation — front bumper corner or grille access, harness disconnect, remount on factory brackets. Confirm ballast compatibility before assuming your existing ballast will carry over without issue.

OEM vs Aftermarket

Xenon beam pattern and ballast reliability are where cheaper reproduction headlights most often fall short on this platform — a genuine OEM unit avoids that risk entirely.

Shipping and Support

Ships boxed with lens protection. If you need the matching right-side unit as well, check our other listings.

Warranty and Returns

30-day return window and a 30 to 90 day functional warranty on ballast function. If you’re ordering this alongside the matching right-side unit, let us know and we’ll confirm both are from a compatible production run before dispatch.

Why Buy This From Us

We test ballast function on every Xenon unit before listing rather than relying on the lens looking clear, since ballast failure is the actual risk buyers face on parts this age.
