yeah in the US our brake lights function as the turn signals and the white strip for the ambers is just blank. it looks cheap. funny enough it was American cars that always had the red turn signals but now its switching to the euro companies cutting costs and not giving us ambers and now the American companies are switching to ambers so they look more upmarket. The new caddy's, lincolns, upper trim-level fords, and Denali's all have amber turn signals now and every Mercedes, BMW, and Audi does not.

As with many government organizations, while they may do certain things well occasionally, that is the exception, not the rule. Like they truly give a damn about us with all those *BLEEP*ing hidden agendas tied to whatever so-called study.
And don't get me started on the still-unproven and bogus man-made 'global warming' crap that is now renamed 'climate change' which has been occurring in cycles for centuries no matter WTF we do. But I will get started to make a point.
Theories like this are nothing but a theory until a peer reviewed study is done - the scientific standard whether you're talking meteorological science or nutritional science. Go ask the founder of the Weather Channel, John Coleman. That means scientists that you can't pick, some of whom hate your guts, get to review your work. If it passes that test unanimously, theory becomes fact.
But those politicos and companies pimping global warming have never had one done 'cause they know it's total BS (and will kill their financial gain.)
My point is this: The not so trustworthy IIHS and Highway-Transpo Safety geeks also don't let anyone review their alleged findings.
We're just supposed to accept it and shut up. No.

..........which is why both NTHSA and IIHS can go to hell.

GET THOSE HEADLIGHTS PROPERLY AIMED!
I thought the report was very interesting. In particular, they noted that they tested cars as delivered from the factory ... and that many of the cars had headlights that were improperly or poorly aligned. They clearly stated that misalignment caused at least some of the poor results they reported, and suggested that drivers have the headlights on their new cars checked rather than just assume they're fine from the factory....
THE GOOD NEWS IS THAT PROPER DEALER ADJUSTMENT CAN GREATLY IMPROVE THESE ACTIVE LED HEADLIGHTS! The active LED headlights are not user-adjustable. I asked my dealer to adjust my headlights up to the legal limit. It turned out that, as delivered, the cutoffs on my "low beam" lights were much lower than the legal limit. That must be the factory setting, because the cutoffs of the "low beam" headlights on a recent loaner 2015 E-Class were even lower and closer.
THE ADJUSTMENT MADE A HUGE DIFFERENCE! The cutoff is a far enough distant that I am longer out-driving my headlights. So far, no driver has blinked his lights at me. When I follow smaller cars, the cutoff is right at the bottom edge of the rear window. So I try to hang back, but the maximum following distance setting of my Distronic Plus seems to be okay.

As they come from the factory, many headlights are aimed too low. The "low beam" cutoff of the active LED headlights is so sharp that the effect is as if a mechanical shutter is coming down in front of the beam. The cutoff intersects the road a very short distance in front of the car. Since no light at all spills upwards from the cutoff, I found that when driving on the dark, wooded roads common in my area, the effect was like driving under a low-hanging bank of opaque black fog!

I see that you're able to get your dealer to do it for you. Did you know how they did it? I was wondering if there is an instruction online somewhere that I could bring to my dealer to get them adjusted. It's way too low right now...

Ha! Glad he's gone too, was embarrassed to post on this forum with that guy floating about. Though best not to respond to trolls like him, or climate change guy anyway. Responding and letting them argue makes them think their rantings are legitimate.

I don't really care if the NHTSA's test was fair or not. No car bearing the three-point star should come equipped with halogen headlamps in the year 2016. It's as simple as that. If Mercedes-Benz is truly serious about living up to its unparalleled heritage and "the best or nothing" credo, then the bean counters need to stand down. Every Mercedes should come equipped with xenons, at minimum. This company lost a massive amount of goodwill during the Chrysler years and, while quality has improved, it's disappointing to see how much work remains to be done.

No "secret sauce"
I find that my active LED headlights are way too low. I had a C300 loaner with static LED and they were much better than my active ones. I asked my dealer to adjust my active LEDs higher for me but he says that they automatically adjust according to the amount of light and there's no way to aim them higher. However, the static ones could be adjusted.

dealers are way too busy to fix such minor issues.
at my dealer, there's a 1.5 week wait whenever i want to schedule for service, LOL.
NY gotta be one of the most unwilling places to help. Even NJ people are much nicer.

they'll fix anything, I complaint about a SLIGHT pulsation while braking and they replaced all rotors and pads. same with my dealer in MA, they replace anything you complain about - I'm sure its so they get good reviews and don't have to deal with the hassle of a customer that keeps complaining

In the meantime, you can try going over your dealer's head to corporate. Before you do that, how do your lights look in manual mode? Have you ever had them out of automatic mode? (No reason why you would, in normal driving.) Are your high beams selected? The stalk has to be pushed forward for high beams to be activated, even in automatic mode. I have found that if I signal with the high beams, the lights remain in low beam only. In urban driving, it could be a long time before I noticed.
