LED running lights look absolutely terrible, they are probably the most Halfords-esque of all new car styling features. Everything seems to have them these days and it just looks so awful.
EU regulations do not mandate LED running lights at all - they simply say you must have running lights. These can quite easily be sidelights just like Volvo have been doing every year.
However Audi decided they needed something brand-identifying like BMW's Angel Eyes, came up with the LED thing, and everyone else copied.
Great :/
