Replace the Bulb or the Entire Headlight Assembly?

[SanTheo]

For vehicles originally equipped with xenon headlight assemblies, it is recommended to replace the entire assembly. If it's purely a xenon bulb issue, the assembly may not need replacement. Definition of Xenon Headlights: Xenon headlights, also known as HID (High-Intensity Discharge) headlights, replace traditional tungsten filaments with high-pressure xenon gas enclosed in quartz tubes, providing higher color temperature and more focused illumination. Xenon lamps generate light by activating xenon gas with high-voltage current to form an arc between two electrodes, which continuously discharges to emit light. While standard automotive bulbs consume about 65 watts, xenon lamps require only 35 watts, reducing power consumption by nearly half. Benefits of Xenon Headlights: Xenon headlights significantly reduce the load on a vehicle's electrical system. With a color temperature ranging between 4000K and 6000K, they far exceed that of conventional bulbs. Offering high brightness and multiple color options, OEM xenon headlights typically feature 4300K, which closely resembles halogen light in color temperature and provides strong penetration, enhancing nighttime driving safety.
