What is led zenon?

I'm not sure what you mean by "led zenon." Are you referring to LED headlights and Xenon headlights? If so, I can provide some information on both:

LED headlights: LED stands for Light Emitting Diode, and this technology is becoming increasingly popular in automotive lighting systems. LED headlights are known for their brightness and longevity, as they consume less power and have a longer lifespan than traditional halogen bulbs. They are also more energy efficient and environmentally friendly, as they produce less heat and use less gas. However, they can be more expensive to install and replace than other types of headlights.

Xenon headlights: Xenon headlights also known as HID (High-Intensity Discharge) headlights, use xenon gas to create a bright white light that is brighter and more efficient than halogen bulbs. They are known for their brightness, visibility, and long lifespan. However, they can be more expensive and difficult to install than other types of headlights, and they can also be more prone to malfunctioning. Additionally, some people find the bright white light of Xenon headlights to be too harsh or distracting to other drivers.
