The pros and cons of Xenon and LED technology

Model: (Various brands) Various
Part: Light bulb

Let's look at the pros and cons of Xenon and LED technologies: Xenon is currently considered an obsolete technology. The light quality is superior to halogen, and only the bulb can be replaced, but it is a technology based on noble gas, requiring a very high voltage electric discharge to ignite; performance is affected by altitude, temperature, and humidity; frequent ignitions quickly wear out bulbs and electronics; maintenance costs are very high; spare parts for older cars are already becoming scarce, and new Xenon systems tend to be "poor" to reduce costs for manufacturers. LED technology (which is the current standard) has a long list of pros: reliability and longevity; superior performance; efficiency and low consumption; simple and economical maintenance (so much so that if a Xenon fails, it is better to convert it to LED). There is also a con: the cooling system of aftermarket LEDs, which we need to be cautious about.
