I have the lighting package and I can easily see the active light system functioning. I haven't however seen the corning light function work. Is there a particular setting the lights need to be in to get it to work? I've tried a variety of settings with the light switch and nothing seems to work.
Here is the description of the Cornering Light Function in the 2014 manual:
The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. It can
only be activated when the low-beam
headlamps are switched on.
Active:
if you are driving at speeds below 25 mph
(40 km/h) and switch on the turn signal or
turn the steering wheel
if you are driving at speeds between
25 mph (40 km/h) and 45 mph (70 km/h)
and turn the steering wheel
Not active:
if you are driving at speeds above
25 mph (40 km/h) or switch off the turn
signal or turn the steering wheel to the
straight-ahead position.
The cornering lamp may remain lit for a short
time, but is automatically switched off after
no more than three minutes.
I have never seen a corner lamp illuminate. Only the movement of the main headlamps as explained in the description for Active Light Function. Should I be seeing a distinct light come on and the "illumination of the road over a wide angle in the direction I am turning"?

OK....here's what I know ( or don't know ) When I purchased my 2011, I read the same stuff in the manual....but there was nothing visible to me..... I later found out that the "cornering light system" was NOT a part of the US configuration for the vehicle. As a result.... i didn't even look for it when I bought the 13 and I know that there is nothing like that on the vehicle.....
Okay, thanks for your reply blittle. Now I at least don't think there is something wrong with my headlights.
Does anyone know what this part of the light is? I haven't seen it illuminate. Originally I thought this might be the cornering light. Perhaps a sensor? Turning on the highbeams just rotates the Bi-Xenons up.

Actually I have the same question, found no purpose of these lights. I think it even has a bulb correct?

This is just a semi-educated guess, but I THINK that what we are looking at is the area where a bulb would be IF the vehicle was not equipped with the "intelligent bi-xe system?"
Okay, it appears this topic has been discussed in the W166 forum. Apparently, what I circled in yellow in the picture above is indeed a cornering light that...get this, is NOT functional in the US.
Below is a thread from the W166 forum complete with pictures and a video toward the end of the thread that shows how the light would function if it were to be operational.

I'm just amused that such a large part of the headlight assembly is non functioning.
I guess Mercedes can't use the cornering lights within the headlight assembly because current Federal regulations mandate that the headlights must work symmetrically. I think we are really missing out because Mercedes is doing some pretty remarkable stuff with these headlights in other parts of the world. I noticed that one of the Mercedes European websites mentions that the headlights go into a fog light mode when you select the fog light switch and the headlights are aimed outward and down toward the lines of the road in an effort to reduce glare and improve the visibility of lane markings.
43221B - I had a 2012 Audi A7 with the LED headlights and they worked just like you state above. The car didn't have true fog lights, it would simply adjust the light pattern as you state. It helped on rainy nights to see lane markings. It also had cornering lights in the headlights, similar to the ones circled in the post above. They only worked below 20 mph when you had your signal on. Again - it was "cool" but I don't miss them. Not sure if it's a federal regulation since it was a normal build for a US destination.

There are various things such as this that "miss out on" because of the complexity of the Fed regs and the certification process. It becomes easier for some of the manufactures to simply say.... "forget it" for the U.S. market.
