Description
【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】1 307 329 293, 307 329 115, 1307329115, 1 307 329 115, 1 307 329 098, 1307329098, 1 307 329 121, 1307329121, 1 307 329 123, 1307329123, 1 307 329 124, 1307329124, 1 307 329 129, 1307329129, 1 307 329 203, 1307329203, 1 307 329 250, 1307329250, 1307329293, 1 307 329 294, 1307329294, 31213765, 31213766, 30678910, 30678911, 8E0 907 391 B, 8E0907391B, 8E0907391 B..【Compatible】it fits for 2006-2008 Cadillac DTS ;2006-2009 A4 / S4 Sedan and Wagon (w/o curve lghting) ;2007-2009 A4 / S4 / RS4 Cabrio (w/o curve lighting) ;2006-2008 Saab 9-7x ;2007-2011 Volvo C30 ;2006-2011 Volvo C70 ;2004-2007 Volvo S40 ;2005-2007 Volvo V50
