The Valeo 6G ballasts are original equipment for late model VW, Audi, and BMW cars with factory HID headlights. Unfortunately, these ballasts have a limited lifespan, often requiring costly replacements outside of warranty. A replacement ballast is available, meeting/exceeding OE specifications and functioning like the original at a fraction of the cost. It's recommended to replace both ballasts and bulbs due to their 2000-hour run time, preventing further issues. Additionally, customers should verify compatibility for their specific vehicle model, as certain makes and models might use different OEM HID ballasts. umnitza's longstanding reputation in the automotive lighting industry assures customers of high-quality products, expert knowledge, and a wide range of offerings.
