High Intensity Discharge (HID) headlamps are superior replacements for conventional heated-filament headlamps that require about 25kV applied to the lamp electrodes to ionize the Xenon gas and "strike" an arc (often implemented with a separate igniter circuit). HID technology simply uses the light emitted when ionized Xenon gas in a sealed bulb changes energy states. Once the gas is initially ionized, the light-emitting arc is sustained by an AC potential of about 90V applied across the electrodes in the bulb. The resulting arc emits light with a high luminous intensity, hence the name High-Intensity Discharge or HID.
