What is a Xenon Headlight Bulb?

Xenon headlights are a type of headlight that uses a gas called xenon to produce a brighter and whiter light.

When electricity is applied to the bulb, the xenon gas produces a bright and intense light that is very similar to daylight.

This makes it easier to see the road ahead, especially in low-light conditions. Xenon headlights also last longer than halogen headlights, which means that you won't have to replace them as often.
