OE Replacement: Valeo 63117180050
OEM Grade: The Valeo 6G ballasts are original equipment on many late model VW, Audi, and BMW cars 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! Save Yourself: Most headlight ballasts and bulbs are rated at 2000 hours of run time and if one just went out, chances are the others aren't far behind. Save yourself the hassle of taking off the bumper again, removing the headlamp, and just replace everything at the same time! Notice: Certain makes and models may use different OEM HID ballasts depending on the production date and/or trim level. It is always best to double check and match the part used on your actual vehicle to ensure compatibility. While we are glad to make any exchanges, we are not responsible for mis-information if you purchase the wrong unit.
