This is what i got from the internet this is old and Im sure both platforms have evolve.

Xenon headlights
Xenon lights, also known as high-intensity discharge (HID) lights, produce a brighter light than halogen bulbs and with far less heat. The blue-white light emitted by xenon bulbs is so bright, it has been known to "blind" other drivers.
These headlights require a large amount of power at the outset to produce their first burst of light, but once fully operational, they require much less energy to maintain constant brightness.
Xenon bulbs have a long lifespan and emit little heat, but they cost more than halogen bulbs.
LED headlights
LEDs are the most recent innovation in headlight technology. Instead of gas and filaments, LEDs rely on small diodes that produce light when electric current excites their electrons. They need an low amount of power to work but do produce a significant amount of heat on the diode. This requires heat control systems at the bottom of the headlight and near other car components. If this system fails, not just the light, but other electronics could be affected.
The small size of LEDs means they can be formed into almost any shape, and their light is naturally directional rather than diffuse, making them an excellent choice for headlights.
