hid lights 300 H I D LightsHID stands for high intensity discharge. High Intensity Discharge (HID) lights, also know as Xenon lights, produce a bright light resulting from an electric arc inside a capsule full of Xenon gas. Many times, HID lighting appears to give off a bluish tint when the bulbs are lit. This technology produces a significantly brighter and whiter light than that of a standard halogen light.
