Why do xenon headlights turn yellow?

[LaAdriel]

Xenon headlights have a certain lifespan. As the usage time increases, the color temperature of xenon headlights drops below 5000K, making them noticeably yellow. Below is an introduction to xenon headlights: 1. Introduction: Xenon headlights refer to high-pressure gas discharge lamps. Xenon headlights are heavy metal lamps that fill an anti-ultraviolet crystal quartz glass tube with various chemical gases, such as inert gases like xenon. Then, a booster increases the vehicle's 12-volt power supply to 23,000 volts instantly. Under high voltage, xenon gas is ionized, producing a light source between the two poles of the power supply. Xenon headlights are known for their energy-saving properties and good color temperature. 2. Advantages: (1) Xenon bulbs have three times the luminous intensity of ordinary halogen bulbs while consuming only two-thirds of the energy. (2) Xenon bulbs use a light color nearly identical to daylight, creating better visual conditions for drivers. Xenon headlights provide a wider range of illumination and greater light intensity, significantly improving driving safety and comfort.
