【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.
