Why do modern cars like the Audi R8 have such bright LED headlights?

Mike Rutherford asks, "Who wouldn't love to own an Audi R8?" I wouldn't. Certainly if it caused a nuisance to other road users. I refer to its LED headlamps. Cars fitted with these eco-friendly lighting units seem to have sidestepped the facility of dipping. Many's the time I've been dazzled by them, dangerously so. My wife suggests I talk to the police. Before I do so, what's your view of LED headlights? Have they been risk-assessed?

LED DRLs are not headlights, they are Daytime Running Lights to enable cars on country roads to be seen so other cars do not pull out into their path. I agree, on many Audis the DRLs incorporated into the headlights as a bit of jewellery are a bit bright. On 2012 Jaguar XFs the DRLs in the headlights self-dim when the turn indicators are used. The best place for DRLs is separate and not over bright, as on the Fiat 500. Or set down low, as in Mercedes-Benz, Porsche, Citroens, Fords and Kias. If you are severely dazzled by LEDs you might have an eye problem, so it's worth consulting a specialist at the risk he may ban you from driving.
