It appears that the regulatory hurdle for the fully functioning digital headlamps in the US may have been cleared. At least according to a news release for the 2027 S-class. What is the likelihood that existing cars with the necessary digital light hardware, like many W214s, will receive a software upgrade from MB?



Article on 2027 S-Class

 

The likelihood is pretty low. Mercedes will be the first German OEM to offer the functionality in the US, and will be the third overall behind Tesla and Rivian. I've had this discussion with my former colleagues at several German OEMs for years now about their plans to retroactively enable this, and the consensus is that it's too vital a safety issue for something to go wrong. So they aren't planning to... at least MBAG and VWAG. You will see it enabled on future cars, though. I believe all MB models heading to Canada now have it enabled.

Part of their reasoning is that DIGITAL LIGHT (and other matrix ADB systems) require precision aiming to function properly and not dazzle other users. Mercedes, in the US, prescribes an analog headlight aiming tool as standard workshop equipment, while Tesla and Rivian now mandate far more advanced digital units, designed for matrix systems. If you have had a headlight replaced, for example, chances are it wasn't aimed properly. Techs also like to just "guess" when a customer complains that their lights are too low, and they'll adjust them up without care.

I have personal experience with this. Years ago, I had to replace one of the MULTIBEAM lamps on my S213 mopf while it was in the US. Mercedes was able to source the EU part from Germany. When it came time to aim, the tech had no clue what he was doing. He put my car on the alignment rack, elevated, and rolled the aimer in front and guessed the needed distance, totally contrary to Xentry instructions. Similar to a second dealer. I lucked out and found a $10K digital aiming tool on eBay for a fraction of the cost new, and just did it myself.

 

No disrespect, but if activating adaptive or Intelligent lighting is a software issue, how does the type of headlight aiming equipment make any difference. The very small sample size of owners who have had third parties unlock advanced features seem happy with the result.
Are the headlamps calibrated differently when digital lights are installed on the assembly line depending on where the car ultimately will be sold. Does MB or the Canadian gov't mandate that all MB dealers have digital aiming tools (I'm assuming that up till now they have not needed them)? What about independent shops? The cynic in me thinks lawyers are involved in the US decision.

 

None taken. This just happens to be an area in which I spent a lot of my time in the industry. The lawyers are definitely involved and have kept several OEMs from implementing this. Volvo is a big one that I know of. I defended one of my previous employers in a situation where a customer illegally coded his car to enable adaptive beams, did not enter the appropriate calibration values, and it momentarily blinded a passing motorist, who subsequently crashed. Granted, a strange circumstance because the idiot had his Instagram handle on his car, so he was easily tracked. But they do take this stuff very seriously, given how litigious the US can be.

And yes, they are calibrated differently. How different it depends on the OEM. MB US lamps have up/down adjustments and generally, less lumen output. RoW lamps have up/down and left/right adjustments. Most modern lamps have a QR or datamatrix code that needs to be scanned, as well, which has calibration data for the lamp itself, from the assembly line. That code stores specific, individualized calibration data for LED components, ensuring consistent brightness and color output. For VAG/VW/Audi/Porsche, the same is true, but their lamps also require values from the digital headlight tool to be entered into the diagnostic software. These values provide an additional point of reference for where pixels are pointing in relation to the lamp position and vehicle. Invalid values (or additionally, bad physical aim) can cause the adaptive beams to mistarget, as in the example of the Audi I mentioned above.

All cars are calibrated at the factory using the same tools, but those heading to the US aren't calibrated as precisely because it isn't needed.

 

I find this a bit hard to rationalize how this actually played out. You pass a car in the dark and their headlights blind you and you crash. The other car that blinded you probably didn't even see you crash and continued on their way oblivious that anything had happened. Even if the car that crashed had a dash camera the likelihood that it picked up any writing on the car is near impossible given it's dark and the headlights blinded the driver. Unless the other driver realized the car crashed and turned around to render assistance could the driver of the crashed vehicle seen the stickers on the car. Even with all this, how can anyone prove that the lights were the reason for the crash.

I live in TN where big trucks are everywhere and have the most ridiculous bright low beams let alone high beams. Yeah, they are blinding and I imagine illegal. If I were to crash due to these lights, I don't see how the other driver would have noticed as we passed each other at a closing speed of at least 60mph and likely much faster.

I have enabled ILS+ from a 3rd party coder in my 2025 E450. They work quite well. I can see the shadows it casts on other vehicles or things it thinks are other vehicles. I have yet to have an oncoming vehicle flash their lights to signal me my lights are too bright. The W214 if equipped with the digital light package has all the necessary hardware to enable this feature. There is likely no technical reason they cannot be enabled after the fact in vehicles that have the necessary hardware. It's not even a software change but a feature toggle from off to on. The only reason MB will not retroactively turn it on is because nobody ever got sued for saying no. It's the safe bet and they have zero interest in doing anything that has the possibility to open themselves to any unnecessary liability. This is my opinion and I can certainly be wrong. I truly hope they enable it in cars retroactively. Even if that means I waisted my money to pay someone else to do what MB has been unwilling to do yet.

 

I don’t recall all the details, but remember the guy with the coded car did stop to render aid. The victim said that the person’s headlights were unbelievably bright at which point the guy said “that’s impossible I have them coded not to do that” or something along those lines. That’s all it took. Apparently they left the scene thinking they weren’t at fault but ultimately insurance and the police deemed them liable. Crazy times.

i hope it never happens to you or anybody else, but enabling out of market features that aren’t certified for the US market puts your vehicle out of compliance with safety standards and could be an issue if someone wanted to make it so. That’s just how the US market is, and is why manufacturers are reluctant to enable these things retroactively.

 

Just because you have your car coded for ILS, doesn't mean they were active at the time of an incident like this. I sometimes have my low beams on purposely and in this case ILS is not on. They could still be blinding to some drivers. I assume the driver with the blinding headlights either represented themselves or had a terrible lawyer in this case. It would be a different if it was an illegal modification that is hardware based. This is software that nobody could prove was on or off at the time of the incident. I'm not disputing the story, but it just seems a bit odd.

 

Ah, but we could. Many modern vehicles do have event recorders - similar to black boxes in aviation. Data showed the feature was active at the time of the collision, in addition to footage obtained from their dashcam. There was also a record of modifications made to the vehicle, since enabling this requires use of VW's official diagnostic tools on that particular model.

I get what you're saying, though. I am constantly blinded by other road users when I drive in the US. It's either the micropenis bros in the jacked up brodozers, poors who can't afford to replace a headlight bulb and drive with their high beams on to avoid law enforcement, or general bad aim (TESLA!) from the factory, or from a replacement.

I suppose the outcome could have been different if he kept his mouth shut, but like so many I see on social, he bragged that it was "impossible" because his wagon was now "Euro spec". This was certainly one of the most interesting situations I dealt with in my career...

 

Do we know for certain that third party activation meets DOT (legal) specs? If re-coding from low beam / high beam to full adaptive still meets DOT standards, such as light intensity, beam width or whatever, then there is no functional reason to NOT offer the upgrade, even if offered at a cost, like activating the dashcam. In a perfect world MB should be thrilled to offer a worthwhile upgrade they were previously prevented from offering due to circumstances completely beyond their control. Thoughts...

 

Yes and no, and it's (unfortunately) complicated. Right now, I don't believe there is software (in the MB world) that enables ILS+ with US-legal beam patterns, permitted lumen output, etc. It does exist in Canada, but their lighting regulations are similar but different. The S Class will first introduce this to the US market.

Third-party coders are likely loading an EU dataset (similar to VW/Audi), which would technically and theoretically not be legal. Disabling the amber side marker, for example, is also not legal.

I hope they can enable this as a future DIGITAL EXTRA, but I'm not certain.

 

Activating full Digital Light features retroactively in the US would be all risk and no reward for MB (and any other manufacturer). No way it will happen in a random software update.

The only possible way it could work is on an individual basis after hardware inspection and calibration by an MB service department, and customer acknowledgment of the new lighting features in their vehicle.

 

While it would save me $500+ from going to an aftermarket installer, imagine what those costs would be to MB dealerships...I'd sign something from MB if they wanted to do it in an OTA update...ha ha

 

I think the answer is much more simple. Car manufacturers are always adding new features to entice buyers to “upgrade” to the latest greatest model. Adding fully adaptive digital headlights to a future E-class, and not updating the software in existing ones, follows that model. I hope we are all wrong and MB provides a simple software change as they do for so many features in our cars. If MB was so worried about liability, I don’t think they do would be doing any software modifications in their cars as a driver can always claim that the change was a factor in driver error (through confusion, distraction, misunderstanding etc.). But MB and other companies modify software all the time, including for features that directly impact safety.

 

LOL, I knew there were lawyers involved. The reward would be happy and appreciative customers, grateful that corporate greed and legal apprehension didn't have such a large influence in modern society. Throw in a smaller dose of over regulation too. What is the evidence from countries that have enabled (embraced even) adaptive systems compared to the older low/high function?

 

^ As you said in a previous post, in a perfect world. In the world we live in, however, it's not hard to come up with a scenario in which MB could be held liable in a blinding light scenario. Don't hate the lawyers...hate the entitled populace with no sense of personal responsibility...

 

Wouldn't that be nice. (Not hopeful).

 

Interesting thread. If the S Class is going to get the anti-dazzle lights, then there is hope for the US.

 

MB has always been a lighting pioneer, especially in other markets. There's no doubt other models in the US market will get it. It is doubtful that it will come to existing cars... although I'd love to be wrong.

 

Maybe MB will see enabling this feature in prior year classes already equipped with the hardware/software as a money making opportunity and charge for activation. I’d pay for it even though I rarely drive at night.

 

Depends on your interpretation of "hope". Sure, in the next generation or facelift version of the E class. But this discussion is more about whether MB will offer an upgrade to the current, deprived headlights, making them fully functional adaptive matrix lights. So far it appears that the consensus is that they will NOT, even if they could.

 

True.

Unfortunately, for "hope" I don't mean 2026 or earlier E-class vehicles. The Mercedes website said that the 2025 E-class was going to have anti-dazzle with the upgraded lights. I was disappointed when I test drove a 2025 All-Terrain and didn't see any evidence of anti-dazzle.

The Digital Light LED's are very good low/high beam lights. They would be so much better if the Federal government permitted their use as anti-dazzle light.

 

There was a recent OTA update (the past week, give or take) to digital lights. Any idea what changes were made?

 

I would bet if they do make it available, you’d have to pay for it.

 

From what I’ve read it was relatively minor to adjust sensitivity thresholds for auto main beams. No additional functionality was included.

 

Yes, there is a small charge and the effects (two of them so far a cool.
