【Premium quality 】made of premium aluminum for better heat dissipation and vibration resistance performance,also with 6 protections against overpressure,low pressure,overheating,no-load,short circuit,reverse connection for more safety and durability.B uilt-in high pressure bag can speed up current conduction speed & save power consumption for fast startup,also can protect high pressure bag from any dust & rain in the engine environment to enhance security. 【Replacement A ballast】It is a crucial part of a fluorescent or HID lighting system. Also does it provides enough voltage and current throughout operation and regulates the electrical current of the light once it is lit. It can act as DC to AC converter so that you can use the normal DC power source in the car to light the bulbs efficiently.The most common cause of HID Ballas failure is long term use, which can resulting in flickering, dipped beam not working or light failed. 【Powerful function】 Waterproof & shockproof performance-the internal circuit board is treated with adhesive glue irrigation , protect internal electronic components from oxidation & aging.It can help your lamp start up quickly. When the lamp is turned on, the ballast provides a surge of higher voltage, then establish an arc between two electrodes on the lamp and reduces the voltage and the electric current. This ensures the light produced is even and steady, without flickering or fading. 【Reference OE】:manufacturer part # 5DV 008 290-00, 5DV 008 855-00, 008290004 ; Audi part # 4E0 907 476; BMW part # 63126907488, 63120150614, 63126916100; Mercedes part # 002 820 23 26; Ford part # 2M5Z-13C170-AA; Maserati part # 980139011; Saab part # 12790592, 12-790-592; Jaguar part # C2S015079, C2S52482. 【Compatible】:the 5DV 008 290-00 ballast fits for 2005-2008 Audi A6 / S6; 2005-2008 Audi A6 / A6 Avant / S6 / S6 Quattro; 2004-2008 Audi A8 / S8; 2003-2005 BMW 5 series (E60); 2002-2004 BMW 7 series (E65 E66 E67 E68); 2004-2006 BMW X5 (E53); 2003-2007 BMW Z4 (E85 E86); 2003-2007 Saab 9-3;please carefully check the fitment below,warranty:1 years.
