Question: what is a xenon light bulb?
Answer: Xenon HID. ... Xenon bulbs can produce a brighter, whiter light than a halogen car, and tend to have a longer lifespan. HID stands for High-Intensity Discharge. The bulb works in a different way to a halogen. Instead of a filament heating up and glowing, HID headlights use electrodes to charge the gas inside the bulb.
