Are the Intelligent LED head lights (the ones with dual projectors) in my C400 adjustable? I feel like they are aimed too low.
Yes, find two light-grey, concave hex-key screw heads, about the size of a dime -- 2015 C300 driver-side headlight adjuster 2015 C-class passenger-side headlight adjuster
If it's already lined up with the adjacent panels, you don't. Actually, you don't have to, even if it's not already lined up with the adjacent panels. But the obsessive/compulsive types around here that want to know how to re-program their turn signals would probably want to line up their hood with the adjacent panels.
i didnt even realize i could adjust my lights mechanically, thought i needed a module or coding. my lights are also too low after i lowered the car (airmatic)

and i didnt realize there' a problem with my 2016 C450 headlights until i got a 2019 C300 loaner, that car light up the road much farther, easier to see and i'm more comfortable to drive faster.
This is a good read. A whole recall for a simple plug, just to prevent people from adjusting their headlights.
Recall Number 15V087000
Recall Date 02/11/2015
Component EXTERIOR LIGHTING:HEADLIGHTS
Summary
Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2015 C300 and C400 vehicles manufactured from June 18, 2014, through September 5, 2014, that fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment." The affected vehicles were assembled with horizontal adjustment mechanisms that allow the owner to change the horizontal adjustment used during the manufacturing process, instead of the proper sealing caps.
Consequence
If the original horizontal adjustment is used to alter the low beam aim, the misaimed headlamp may not properly illuminated the road or cause increased glare to oncoming drivers, which increases the risk of a crash.
What Owners Should Do
Mercedes-Benz will notify owners, and dealers will replace the horizontal adjustment mechanisms on the headlamps with sealing caps on the affected vehicles. The recall began May 23, 2016. Owners may contact Mercedes at 1-800-367-6372
So they would basically seal it and prevent you from adjusting it... no thanks lol

If horizontal adjustment means "right and left adjustment," nobody here has expressed any interest in horizontal adjustment. Owners have always been able to adjust vertical aim. Yet the position and type of adjusting screw shown in the images you included indeed look like what I call vertical adjustment screws (of which I submitted images). If M-B is really trying to end vertical adjustment by owners, it is one more effort to end adjustment/maintenance by owners. (Of course, the ultimate objective is to end DRIVING by the owners!) Whatever, I will not be letting my dealer perform any such recall. I go to an independent shop now anyway.

Never fear, its an old recall released in 2015/2016. I just looked at my dynamic led headlights on my 2015 C300 and there is NO adjustment screw in that area, only a plastic circle.
i always wondered this myself, funny, i was just thinking about it the other day... driving at night i kept thinking "i think my lights are aimed too low, i can't see THAT far ahead".... in my 2006 subaru, i had an adjuster wheel inside the cab - they put it in so if you put **** in your trunk and weighed down the back, you can adjust the headlights down so you arent blindning anyone... i was surprised a car that is 10 years newer didn't have such a cabin adjustment. guess its back to the old school days of doing the **** manually under the hood. i need to do this.

I can confirm i was able to adjust the "vertical" up and down aim of my headlights using the pic above. My car has airmatic and because i am lowered, it caused it to be significantly aimed low, i have sinced adjusted and i can finally see the road!
The holes are hexagonal. So, yes, a flat-blade screwdriver, or even a Philips screwdriver would certainly damage them. Such damage will absolutely scream "shoddy maintenance" to a prospective buyer! Hex keys (aka "hex wrenches" or "Allen wrenches") are not very special tools. A set of hex keys comes with many socket sets, even the cheapest (like mine!). You just have to experiment to find the right size.
Just an addit to this - if you're doing a rear camber arm change to move to adjustable rods, make sure you note the angle of the leveler headlight sender arm BEFORE removing it from the original solid arms.
The critical angle is the black arm on the sender, which is controlled by the sender rod from the bar itself (pictured).
Replicate the original as best you can. If you don't - you'll be at tree top level on low beam for sure.

When adjusting my headlights again, I noticed the the adjusters can indeed use a Philips screwdriver too. At the bottom of each Allen wrench hole is a socket for a Philips screwdriver. So either an Allen wrench or a Philips screwdriver can be used.
I have a 2014 C250, and recently I discovered the LED headlight on the right hand side to be angled lower towards the ground (see photo: https://share.getcloudapp.com/E0uzDQpY). Also when the car starts, the right hand headlight no longer auto-adjust (dip then return to normal position) where as the left side still does.
I have tried the method outlined in this thread to manually adjust the angle, but turning in either clock or anti-clock direction do not seem to cause any adjustments, on both headlights!
Some help and advise would be very much appreciated!
