What Causes Xenon Headlights to Stop Working?
1 Answers
Car xenon headlights may stop working due to bulb damage, blown fuses, or headlight controller failure. Below are the relevant details: Introduction to Xenon Headlights: In the automotive lighting field, they are also known as HID (High-Intensity Discharge) headlights. They replace traditional tungsten filaments with high-pressure xenon gas enclosed in quartz tubes, providing higher color temperature and more focused illumination. Xenon lamps generate an arc of light by activating xenon gas with high-voltage current, creating continuous discharge and light emission between two electrodes. Working Principle: The illumination principle of xenon headlights involves filling a UV-cut, anti-ultraviolet quartz glass tube with various chemical gases, predominantly xenon and iodides. A booster then instantly increases the vehicle's 12-volt DC voltage to 23,000 volts, exciting the xenon gas electrons inside the quartz tube through high-voltage oscillation. This creates a light source between the two electrodes, a process known as gas discharge.
