What is the difference between Xenon lamps and LED lamps? The aim is to get as close as possible to a light that resembles midday sunlight; LEDs come very close as they emit a very white beam of light. Xenon has a control unit that converts the car's 12 volts into 25,000 volts; additionally, inside the Xenon bulb, there is a gas (Xenon, in fact) that is electrically excited, which is why it takes a few minutes to reach full brightness.

They definitely last longer than halogen lamps. LEDs have a much higher light output than Xenon, producing a cold light, but they have a fan to circulate air because the electronic board managing the LED heats up significantly.

They are practically eternal, but if they were to fail, currently, it is not possible to replace just the bulb; the entire headlight must be replaced.
