I am purchasing an Audi A6.
We wouldn’t say that LED headlights are “better” at night, but they are more efficient, so they require less energy than xenon lights. Some of us also think they look cooler. Xenon high-intensity-discharge lights are brighter and more illuminating, though some of that advantage can be erased by using more LEDs.
The efficiency aspect is why LED headlights are available on cars such as the Toyota Prius hybrid and Nissan Leaf electric car and will be offered on more vehicles in the coming years. A recent report said LED lights can add six miles to the driving range of an EV, a significant gain considering most EVs can travel less than 100 miles on a single charge.
Automakers are looking for ways to reduce the amount of energy it takes to operate their vehicles, so LEDs will become more common. One obstacle holding them back is cost, which is considerably higher than halogen lights and somewhat higher than xenon lights, which aren’t cheap, either. Matching the output of xenon lights requires adding more LEDs, which only raises the cost.
