Universal H4 Zenon Headlight System

High Intensity Discharge (HID) systems are much brighter and run cooler than other lights, and last much longer.

HID systems replace the light bulb filament with a capsule of gas. The light is emitted from an arc discharge between two electrodes inside a quartz glass capsule. The light produced more closely approximates the color of natural daylight. The bulb included is either a 6000K or a 8000K, the higher the number the more of a slight green/blue look. If the type makes a difference to you, add a comment when ordering.
