Multibeam LED Capabilities in the US

I’ve been doing some research in an attempt to find out exactly what headlight technology is in our 2019 E Coupes and Cabriolets with the “Exterior Lighting Package – LED Intelligent Light System and Adaptive Highbeam Assist.” I haven’t been able to get a definitive answer from my dealer or MB online support.

My understanding (and hope) is that the headlights in the 2019 E Coupes and Cabriolets with the Exterior Lighting Package are the full Multibeam LED with 84 individual LEDs as available in Europe (the headlights are labeled “MULTIBEAM LED”), but no one can confirm this. It appears that some of the capabilities of the headlights and system are disabled in the USA due to NHTSA regulations, specifically the ability to leave the high beam on all the time and let the lights automatically dim only the areas necessary not to blind oncoming cars, cars in front, or to reduce roadside glare from signs. Current regulations only allow the automatic high beam system to turn the high beams on or off, not adjust individual areas. It sounds as if NHTSA is ready to change the regulations to allow this Adaptive Driving Beam Technology. The comment period for the regulation change ended in December 2018. https://www.federalregister.gov/docu...ated-equipment

There are many MB websites that explain the E Class Multibeam LED lighting. They do a great job of explaining the technology and capabilities. None mention reduced capabilities in the USA. Here is a very good description of how the lighting system should work. https://www.mercedes-benz.com/en/mer...uture-e-class/

The added safety provided by the MULTIBEAM LED technology becomes apparent above all in real traffic situations: in contrast to static high-beam systems, some of which have long ranges, MULTIBEAM LED also supports the driver when there are other vehicles in the field illuminated by the headlamps. Because it masks these out of its light distribution specifically within a fraction of a second, it is possible to drive with main beam switched on at all times. This assures the driver of the best possible light performance at all times, without dazzling other road users.”

I guess the main question is, do we have the same headlight hardware that they have in Europe, only with some reduced capabilities due to regulations? If that’s the case, is it just a matter of activating the full capabilities in the software if the regulations are changed to allow this technology in the US?

I would love to know this, too. But $50 says that even if it IS the same hardware with crippled software, MB’s answer will be to just buy a new car — no software update.

If it’s the same hardware, you’d think it would be as easy as turning something on in configuration settings to make it work. The software should already be installed, just not turned on. I agree with you though that MB is very reluctant to update software. Maybe they’ve loosened a bit with the introduction of over-the-air update capability. Remote parking is the same situation. It’s available in other countries. Should be a matter of activating it in our cars if and when regulations allow.

Regulations in the US already allow for remote parking. Tesla and BMW have offered this feature in many of their cars for several years now. I don’t understand why Mercedes has not activated this feature for their US cars.

I emailed MB support about multibeam headlights. Originally they said that my headlights were not mulitibeam headlights. When I pointed out that they are labeled “MULTIBEAM LED” (and sent a picture), this is what they said:

Thank you for your additional email.

While you are certainly correct, the labeling does state"Multibeam LED", we have verified with our product team that the U.S. does not support this function (nor is it advertised as such). It is confirmed your vehicles headlamps are and function as LED Intelligent Light System headlamps.


As we understand the confusion from the label stating otherwise, please be advised we have brought this to the attention of our product management team for internal review

We appreciate the opportunity to respond.

Kind Regards,

I’m not really confident they know what the headlights are.
