Tesla appears ready to enable the matrix headlights in the new Model 3
Not a Tesla App
According to a new document, it appears that Tesla is finally preparing to introduce support for adaptive headlights. However, it looks like support may be limited to the upgraded Model 3, at least initially.
Support for Matrix Headlights?
The documents from European certifications, dated November 8, 2023, indicate the upcoming addition of "Adaptive Main Beam" headlights for the new Model 3, which is expected through an over-the-air software update. This revelation, initially shared by @eivissacopter (via DriveTeslaCanada), suggests that older models like the original Model 3 and current Model Y may not receive this update despite some of them having matrix headlights.
Update: It’s not completely clear whether the new Model 3 contains full matrix headlights like some other models or if they simply have an adaptive beam.

The decision to initially limit this feature to the upgraded Model 3 is interesting. There’s no reason to believe this feature won’t eventually be added to other Tesla models that include matrix headlights, but the documents specifically mention the new Model 3 and its adaptive headlights. It should be noted that Tesla likes to test new software with a small segment of owners initially, however, the new Model 3 does feature new headlights. So it’s not clear if this is a software strategy or if there are changes in the new Model 3’s headlights that allow Tesla to finally enable them in Europe.
What Are Matrix Headlights?
Matrix headlights, also known as adaptive headlights, are an advanced automotive lighting technology designed to improve nighttime driving safety and visibility. They consist of multiple LED elements or individual light sources that can be controlled independently. This fine control allows the system to adapt the light distribution pattern based on factors such as traffic conditions, road curvature, and the presence of other vehicles.

The primary benefit of matrix headlights is their ability to selectively dim or deactivate specific LED elements to create "shadows" or dark areas in the beam pattern. This helps avoid dazzling oncoming drivers or those in front of the vehicle while maintaining optimal illumination of the road ahead. For example, when an oncoming vehicle is detected, the system will adjust the light pattern to prevent the high beams from shining directly into the other driver's eyes. The rest of the road, however, remains well-lit, ensuring clear visibility for the driver.
Varying Standards Globally
Globally, the rollout of these adaptive headlights will be subject to varying automotive regulations. Different countries have different standards for automotive lighting, and Tesla will need to navigate these as they introduce and expand the feature's availability. The European certification is crucial, as Europe often has more stringent automotive standards, potentially making it easier to introduce the feature in other markets afterward.
Customer Response
Adaptive headlights, a feature in luxury vehicles for some time, are now becoming more mainstream. This technology's primary benefit is safety. By dynamically adjusting the light beam according to steering input and its surroundings, these headlights significantly enhance night-time visibility and reduce the risk of accidents on curvy roads.
Customer response to this development will be critical. While some Tesla owners might be disappointed that their existing vehicles won't initially receive this feature, new buyers will likely find it a compelling addition. This dynamic could influence customer loyalty and brand perception, factors Tesla must manage carefully.

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.
