I guess this could have been covered but a search has proven fruitless in providing an answer.

Is there law or legislation that controls DRL?

I know for indicators and headlamps there are positioning, output, pattern and "dazzle" criteria but it would seem that factory fit DRL are completely up to the factory.

The reason i ask is that i regularly see a Hyundai with only one side lit. These surround the (front) fog lamps. Obviously its frowned upon driving with front fogs on all the time so why is it ok for DRL? and only one at that?

The other (and the reason for my asking) is brightness. I am rather tired of being dazzled in broad daylight by a Megawatt of LEDs on the front of an Audi, Mercedes or (as this morning) new 911 (i have inadvertently highlighted that the worst offenders appear to be the German brands).

Why the hell are they so bright? There is no need to burn out the retina of oncoming drivers surely?
