Xenon lights are gas-discharge lamps used as headlamp light sources in vehicles, offering increased luminance and color temperature compared to halogen bulbs. These systems utilize an electric arc between tungsten electrodes within a xenon gas-filled bulb to produce light. Operation requires a ballast to provide high-voltage startup and regulated current. Xenon systems frequently incorporate projectors for focused beam patterns and may include auto-leveling and washing systems to maintain optimal performance and visibility. Color temperature typically ranges from 4300K to 6000K, influencing perceived brightness and clarity.
