- Mercedes Digital Light boosts brightness by 40 percent overall.
- New micro-LEDs cut energy use in half while adding features.
- Road projections display alerts like snow or lane warnings.
Mercedes is consistently trying to improve its headlight technology, and now we have even more proof of that. Late last year, it shared how it would make them easier to replace and work on. Today, with the introduction of the facelifted S-Class, that older announcement is even more impressive.

The flagship sedan is now available with the brand’s latest generation of Digital Light, and it packs 25,000 micro-LEDs per headlamp to light the way. The figure alone hints at just how sophisticated the system has become.
What 25,000 LEDs Actually Do
At the heart of the upgrade is a new micro-LED lighting module powered by a high-performance chip. Mercedes says the result is an illumination field that’s around 40 percent larger than before, with noticeably higher brightness and sharper light distribution through corners.
The compact nature of this new micro-LED setup has also allowed Mercedes to reduce headlamp weight by more than 25 percent, thanks in part to a simplified design that uses a single control unit. All of the lighting software is now integrated into the company’s MB.OS architecture and developed largely in-house, giving Mercedes tighter control over how the system performs and evolves.
At full illumination, it can cast light 1,983 feet, or about 605 meters, ahead of the car. That’s almost the length of six football fields, which span roughly 2,160 feet or 658 meters in total. But raw distance or power isn’t the only story here.
Adaptive Light That Listens
The real party trick is just how articulate it can be. For example, the high beams can dynamically swivel based on camera input and map data. That enables it to avoid blinding others while fully illuminating the actual path ahead. The partial high beam, now available in the USA., has also been refined to better detect poorly lit road users.
On top of that, the headlights can actually cast images onto the road. This projection capability is part of Mercedes’ optional Digital Extra package. The projection function can cast everything from lane departure alerts, wrong-way driving warnings, and a new cold-weather symbol that displays a snowflake on the road in front of you when conditions turn icy.
Construction zone lighting has evolved into a narrowed-lane light that activates automatically when reduced lane widths are detected. Owners can also enable animated lighting sequences, with updated “Digital Rain” and “Star Wave” designs greeting drivers when locking or unlocking the car.
Less Energy, Easier Fixes
Keep in mind that all of this is happening in a headlight that is effectively increasing light output while reducing energy usage by half. In case all of that makes you worry about how much a replacement might cost, and let’s be clear, it should… don’t forget the announcement last year.
Mercedes is working to ensure that headlights like this one are easier to repair and replace by using screws in manufacturing rather than glue. While specific details are still unconfirmed, one of the technical diagrams released hints that the new S-Class headlights will feature screw-fastened cover lenses. So long as the internal components prove reliable, this seems like a win-win for everyone.

It’s also worth noting that Mercedes validated this entire lighting system in a dedicated light tunnel at its Immendingen Testing and Technology Center. The 328-foot drive-through facility replicates real road markings and layouts in controlled conditions, allowing engineers to fine-tune beam patterns and projection behavior with repeatable precision, regardless of weather or time of day.
