The first-gen Model 3 and Model Y will soon have support for their matrix headlights
Not a Tesla App
According to a new document in the EU, Tesla is preparing to enable its matrix headlights on the current Model Y and first-gen Model 3.
The document, dated January 3, 2024, reveals that Tesla is introducing adaptive high-beam support to these vehicles, similar to what they recently released on the new Model 3.
A similar document was leaked in December that showed that Tesla was looking to add adaptive high beams to the new Model 3.
Software Update
In Tesla software update 2024.2, Tesla introduced support for adaptive headlights in their newest vehicle, the new Model 3.
While this was the first Tesla vehicle to receive support for adaptive high beams, it left many vehicle owners wondering whether Tesla would enable support for matrix headlights that have come on vehicles for several years.
Supported Vehicles
According to this document, the approval is only for the Model 3 and Model Y. However, it’s almost certain that the update will also arrive on the Model S and Model X as well, although it could come in a separate, later update.
The first Model X vehicles with matrix headlights were delivered in June/July of 2023, while the Model 3, Model Y, and Model S have had matrix headlights for a longer period. Support on the Model 3 and Model Y has varied by region and model, so the best way to tell whether your vehicle has matrix headlights is to look at them. If you see a large, round projector lens like the image below, your vehicle has the new matrix headlights.

Video of Adaptive Headlights on New Model 3
X user m.jr.88 posted a video (below) of his new Model 3 that has support for the new adaptive high beams feature. In the video, you can see how select parts of the road brighten and dim as vehicles approach.
Will It Be Available Outside of the EU?
Headlights play an important role in vehicle safety and therefore adaptive headlights are often highly regulated by safety agencies. Due to the leaked document, it appears the feature will be available across the European Union, however, it’s not immediately clear whether it will be available in other regions at the same time.
In 2022, the NHTSA issued a ruling that automakers could install adaptive headlights in their vehicles. However, there could be specifications that must be followed in the U.S. or another region that could differ from EU requirements.
Tesla would without a doubt want to make this feature available in as many regions as possible; however, potential adaptations may be necessary to align with local market nuances and regulatory requirements. At this time, we would expect matrix headlights to become available in the EU soon, with other potential markets available at the same time or soon thereafter.
Release Date
The original document for the new Model 3 was dated November 8th, 2023, so it was about two months before Tesla introduced the update that enabled adaptive high beams on the 2024 Model 3.
If Tesla follows a similar timeline, we may see support for matrix headlights in the next 4-6 weeks. Tesla could add it as soon as the next major update, which is expected to be version 2024.6 or 2024.8.
Update 2024.2, which includes support for the new Model 3 is still in the early stages of rolling out with only about 1% of Tesla's fleet having access to the update. However, we'll likely see bigger waves roll out in the next couple of weeks.
Adaptive High Beam Release Notes
The release notes for adaptive high beam support in update 2024.2 states that the high beams will now adjust to reduce glare for other drivers and cyclists. It goes on to say that by detecting road users and selectively dimming individual pixels of the headlights, the high beams can remain on longer and provide better visibility.
The new adaptive high beam feature is disabled by default but can be enabled in supported vehicles by going to Lighting > Adaptive High Beam in the vehicle's settings.

Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
