Both BMW and Audi offer laser lights on some of their top-range models, a technology which was developed by Audi for endurance racing in LMP1 prototypes. The main reason for the effort was that they provide better illumination and longer range than xenon or LED lights, as well as allowing for some very fancy features. For example, if they're on 'high beam' and encounter an object, the lights will only be dimmed where they reach the object, while the remaining illuminated area will still be on high-beam.
