Specs At A Glance

Good To Know

Q: Can I replace just the ballast and reuse my old bulb? A: Yes, if the old D3S bulb still works, the ballast can be swapped on its own. The included bulbs are a convenient spare.

Q: How do I confirm this ballast matches my car? A: Check your current ballast for part number 8K0941597E before ordering. HID systems vary across trim levels and model years.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
