Xenon headlights also known as HID ( high intensity headlights ) are brighter than other headlights and don't produce as much heat. They are very desirable and are mostly featured on newer and high-end cars. They are more expensive than other headlights which is their only drawback.
Very desirable because of their brightness in lumins & long distance visibility. Aircraft use these. I had them installed in my car, but because of higher wattage sometimes they require a ballast, & check the laws for brightness for the street allowed. Off road types are illegal for street use & have to be covered.
And use LED's on everything else to match bright whiteness.
