Xenon headlights, also known as HID (High-Intensity Discharge) lights, are a type of automotive lighting that uses an electric arc to produce bright light. They are known for their intense brightness and longer lifespan compared to traditional halogen bulbs. The light emitted is often a bluish-white color, which can improve visibility during nighttime driving. These headlights operate by passing electricity through xenon gas, which creates a bright light when ionized. Xenon headlights are commonly found in modern vehicles and are appreciated for their efficiency and ability to illuminate a wider area, enhancing safety on the road.
