The Sportiva HID Conversion Kit is a revolutionary concept in automotive light that provides 3 times more light on the road compared to traditional halogen headlights. Each light uses a tube of Xenon gas, and small amounts of other noble gases, placed between two high-voltage electrodes that emit bright bluish/ white light then electrodes are activated. High quality German designed ballasts are used to regulate the flow of electricity providing a high intensity beam that never fluctuates.
