HID stands for High Intensity Discharge. It refers to lighting technology that relies on an electrical charge to ignite xenon gas contained in a sealed bulb. Xenon’s bright white light is more nearer to natural daylight and helps reduce the eye fatigue normally experienced when driving long distances at night.* This is a revolutionary concept in automotive light that provides 3 times more light on the road and improve your view of road signs, other vehicles, intersections, and objects on the road compared to traditional halogen headlights. I opted to go with the single beam HID kit too and love it, they are cheaper on ebay but I wanted a warranty so I got it here. sealed beam conversion kits , or you can try one of the vendors.
