Audi S4 A4 B7 Front Projector Xenon HID Headlights Lamps Lights OEM

Fitment and Compatibility

This is the front projector Xenon HID headlight setup for the Audi S4/A4 B7 chassis. The B7 generation predates the B8 by one full redesign, so confirm your A4/S4 is specifically the B7 (roughly the mid-2000s body style) before ordering, since B7 and B8 headlights share no mounting or electrical compatibility despite both being A4/S4 badged cars.

Technology and Features

Projector-style Xenon HID headlights on the B7 give a sharper beam cutoff than the reflector-style halogen setup that was standard on lower trims of this generation, which is part of why Xenon-equipped B7s are sought after on the used market. The projector lens focuses the HID output into a more precise pattern than reflector housings.

Condition and What’s Included

Inspected for projector lens clarity, ballast function, and housing condition before listing. On a chassis this age, ballast reliability is the main concern buyers should check for, and this unit has been function-tested rather than sold as-is.

Installation Notes

Standard bolt-in removal and installation process for B7-generation headlights — front grille or bumper corner access, harness disconnect, remount. Confirm your factory ballast is compatible with this housing generation, since B7 ballasts had running changes across the production years.

OEM vs Aftermarket

On a chassis this age, genuine Xenon projector housings are increasingly scarce, and quality varies widely across aftermarket reproductions for the B7 specifically — beam focus accuracy is the most common complaint with cheaper alternatives. An OEM unit like this sidesteps that risk.

Shipping and Support

Ships boxed with lens protection for transit. Reach out if you want to confirm your exact B7 trim and Xenon spec before ordering.

Warranty and Returns

Standard 30-day return window and a 30 to 90 day functional warranty on ballast operation. Given the age of the B7 platform, we recommend testing the unit within the first couple weeks of install so any latent ballast issue surfaces while you’re still well inside the warranty period.

Why Buy This From Us

On a chassis this age, ballast reliability is the make-or-break factor, and we function-test it specifically rather than assuming a good-looking lens means a good ballast underneath.
