2013 ML LED headlight
One noticed question needed help:
On the official website and brochure, the LED headlights are definitely "white".
How come they are "orange" now?

Not try to be picky, but believe "white" would be nicer.
Thanks, guys.
Attached are the photos of mine and one from web.

Just like using red LEDs for turning signal instead of amber, this is just a marketing or aesthetic decision by Mercedes USA.

It was mainly due to the resistance by US manufacturers, and their usual claim was that there was no evidence that amber turn signal was any safer. But National Highway Traffic Safety Administration (NHTSA) had a study in 2009 and concluded that amber turn signal did indeed reduce crash. There were some noises about possibly mandatory amber turn signal, but that went nowhere.
What's more puzzling was all the German car manufacturers (Mercedes, BMW, Audi etc) using red turn signal when their original designs use amber! To save a few bucks? They have to go out of their way to switch the turn signal to red just for the North American market when amber signal is also perfectly legal in US. And I thought that safety was supposed to be high on their priorities - definitely not in this case.

As you can see from my signature what I think about the whole situation. That orange light/ reflector drives me nuts and it such an eyesore.

As for the rear turn signals, there are specific requirements with respect to bulb intensity, surface area, etc. US regulations require a brighter bulb and a larger surface area for the rear turn signal than does the EU. In many cases, this is why manufacturers use red instead. Audi is an excellent example - they do this on most of their vehicles and they often flash both the brake light and the signal light to achieve the minimum surface area requirement in USA.
So, for once, don't blame MBUSA. Blame FMVSS-108.
Edit: Current Gen 5-Series - note the 3 amber LEDs (enough to comply):

For the ML, the torch could have been white in US/Canada, but they would have had to add another amber light source to the headlight (similar to what I showed above with the 2013 5-Series). It is cheaper and simpler to have one headlight design and simply modify the bulb color to comply globally.
In Canada I have only seen yellow.........Q5 was my first pick till I knew ML was changing.
We need to special order active option on the bixenons for Q5 too. $200
