Do full LED headlights on an Audi A6 project farther than xenon headlights?
do not necessarily project light farther than halogen or xenon headlights because that is limited by government regulations, Audi says. LEDs are brighter and cast light that is closer to daylight than other types, making them easier on the eyes for oncoming drivers. The biggest benefit of LEDs is reduced energy consumption — up to 80 percent less than halogen by some estimates, which is why LEDs are frequently installed on hybrid and electric vehicles. The cost compared to halogen and even xenon headlights is the biggest disadvantage of LEDs, so aside from hybrids and EVs, you find them mainly on luxury brands.
