This is a brand new EpAp HID xenon ballast module, designed to replace the factory unit in several Audi models like the A3, A4, Cabrio, and TT.

It's a direct replacement for part numbers like 1 307 329 154, 8E0 941 329 A, and SHL-2-5.

This kit is for D1S bulbs and includes the ballast unit itself.
