A7 helps light up the dark, long and winding roads

Car manufacturers are vying with each other to make better and brighter lights. However, the problem can be - and I often get lights flashed at me because people think I have full beams on - that strong lights can dazzle oncoming drivers.There are systems, and I've experienced them in Mercedes in particular, which automatically dim. They are brilliant.Now Audi have come up with what they call Matrix LED headlights. These light up the road but avoid glare for those driving against you.
