OEM GRADE: The Mitsubishi W003T18471 ballasts are original equipment on many modern Audi/VW vehicles that come with factory HID headlights.
UNFORTUNATELY: Headlight ballasts, like most car parts have a rated lifespan and sometimes don’t even make it that long. Replacing them outside of warranty is never cheap either! This part usually runs about $400 from the dealership…ouch!
GOOD AS NEW! This replacement ballast is designed to meet/exceed all OE specifications and will be a direct replacement for the factory unit. It is not OEM but fits and functions identically for a fraction of the price!
