Tesla has recently committed new code to its Light Show Github repository that reveals several additional Lightshow features and shares specifications for others.
Tesla hosts the software for building Lightshows on GitHub, an open-source code repository. The new code was added five days ago, but given that this is a change to the actual software and not an on-vehicle change, we’re not sure whether the features below will be available for immediate use or will be available in a future software update.
Up to Four-Hour Long Light Shows
The feature update is pretty extensive and, for the most part, is focused on the Cybertruck and Model 3 Highland, but also features changes for other Tesla models.
There’s one general change, which now lets you create Light Shows that are up to four hours in length — yes, that’s really long. In the Holiday update, Tesla mentioned that Light Shows can now be longer, but this recent commit makes it seem like Tesla is essentially removing the limit of how long a Light Show can be.
Front & Rear Light Bars
On the outside of the Cybertruck, you’ll now be able to control the front light bar, but what’s even better is that you can control each of the 60 LEDs individually. The rear light bar is seeing similar improvements, letting you control each of the 52 LEDs individually.
This feature alone is going to create some amazing Light Shows, anything from which has 60 individually configurable LEDs each. The rear light bar has 52 individually controllable LEDs as well.
This alone is going to inspire some really creative designs, such as a Knight Rider-like animation as seen on Rivian.
These are, of course, locked to just white for the front light bar and red for the rear, but Lightshow designers will be able to configure how bright each individual LED is and feather them up and down in brightness.
As we saw in the absolutely epic Tesla octa-truck Lightshow, the off-road lightbar is also controllable on vehicles that have it equipped. For now, that’ll just be Foundation-Series Cybertrucks, but the lightbar has been confirmed to be compatible with the non-Foundation-Series vehicles once it arrives in the Tesla shop later this year.
The off-road lightbar has six segments - two side-facing ditch lights and four forward-facing lights. Although you won’t be able to address individual LEDs here, you’ll be able to control each segment (six total) and brightness.
This feature was added as part of the Holiday update, so it should be available for all vehicles on 2024.44.25 and higher.
Center Display Color
Over on the interior side, designers will get full RGB control for the center display. Even when viewing the light show from the exterior of the vehicle, the center display will light up the interior in any color of your choice, letting you add festive colors to your Light Shows.
The interior display is also available on the Holiday update and is available for all vehicles, including legacy Model S and Model X vehicles that support Light Shows.
Ambient Lighting
This one has been a long time coming, but you’ll finally be able to control the vehicle’s ambient lighting feature on the Cybertruck and new Model 3. The accent lights are split into five segments and are all controllable RGB, so you can set each section to a different color if you want. The sections include center front, left and right front, and left and right rear.
These are some massive additions to Tesla’s Light Show feature, and they’re arguably some of the best. The individually controllable LEDs in the light bars and the ability to choose colors for the first time will undoubtedly create some of the best Light Shows we’ve ever seen.
Unfortunately, Christmas is behind us now, but we’re sure developers will find other holidays that take advantage of colors, such as Independence Day.
Light Shows bring the Tesla community together, and they’re one of the most distinctive Tesla features. Enjoy the awesome Christmas Light Show compilation below. Thanks to Rhys Samson for sharing these Light Show changes with us.

Tesla’s VP of Charging, Max de Zegher, recently confirmed on X that the first 500kW Supercharger sites are coming soon. These next-generation chargers will not only support the Cybertruck charging at 500kW, but they’ll also be more cost-effective to deploy than previous models.
Late last year, Tesla indicated plans to accelerate Supercharger deployments, with many future locations featuring V4 cabinets. Some sites are already being equipped with V4 posts, offering improved charging capabilities, but the V4 cabinets allow Tesla to get even more power to each stall.
500kW Charging
Tesla recently enabled 325kW charging for the Cybertruck at compatible Superchargers across North America - specifically those with V4 posts and V3 cabinets, which are typically referred to as V3.5 Superchargers. The upcoming V4 Superchargers will also have a V4 cabinet, which will take this even further—delivering up to 500kW per stall.
While the increase to 325kW has already improved charging times by approximately 3–5 minutes, depending on the vehicle’s state of charge (SoC), the jump to 500kW is expected to have an even greater impact. With this upgrade, the Cybertruck could potentially charge from 10% to 80% SoC in under 30 minutes—an impressive feat for a vehicle with a massive 123kWh battery pack.
The vehicle’s ability to maintain a high level of charge current can make an even larger difference, so we’ll have to see what the charge curve looks like at these new 500kW chargers.
One of the biggest advantages of the V4 cabinet is its streamlined design. It can power up to eight charging posts—twice as many as the V3 cabinet—reducing site complexity and minimizing the amount of electrical work needed between the cabinet and the posts. This results in a smaller footprint and a more efficient installation process.
Tesla has optimized deployments by pre-mounting Supercharger posts on factory-made concrete bases, making them ready for quick installation. With this approach, Tesla is able to install each post for less than $40,000, according to Max de Zegher.
This is a fraction of the $225,000 per stall cost recently revealed in a contract awarded to Revel Charging. This massive price difference benefits both Tesla and site owners, allowing for faster and more cost-effective network expansion.
Lower costs also mean potential savings for customers, who will enjoy cheaper and faster charging. With the first full V4 sites set to roll out soon, it will be exciting to see how quickly the Cybertruck can charge. Looking ahead, future Tesla vehicles with 800V high-voltage architecture could also take advantage of these next-generation charging speeds.
Supercharging is fast and convenient, but there are times when a station reaches full capacity, requiring drivers to wait for an available stall. When there are only a few vehicles in line, the wait is minimal, and figuring out whose turn it is to charge is straightforward. However, long queues can form during peak travel times or in high-traffic areas, leading to confusion and frustration as vehicles cut the line.
Currently, there is no official system for managing Supercharger queues—drivers rely on informal, self-organized lines. While many follow an unspoken order, disputes can arise when some claim they arrived first or attempt to cut ahead.
Urban Superchargers in cities like Toronto, Los Angeles, and New York often see long lines during busy hours, with drivers doing their best to maintain order. A structured queuing system could help streamline the process, reducing conflicts and ensuring a fair, organized charging experience for all, and that’s exactly what Tesla is about to implement.
Virtual Queue
The Tesla Charging account on X has confirmed that it plans to introduce a Virtual Queuing system, with a pilot program set to launch at select Supercharger sites next quarter. While Tesla has yet to specify which locations will be included, it’s likely the initial rollout will take place in the United States, where the company typically begins testing new charging initiatives.
Tesla says that if the pilot program receives positive feedback, they will expand the system to more Superchargers this year.
The goal of Virtual Queuing is to improve the charging experience whenever wait times occur. According to Tesla, this would apply to roughly “~1% of cases,” though many high-demand Supercharger sites frequently experience long lines. While some remote locations may see little to no wait times, busier stations could greatly benefit from a structured queuing system.
Potential Implementations
While Tesla hasn’t detailed exactly how the Virtual Queuing system will work, there are a few likely possibilities. One approach could involve locking a vehicle’s VIN into the queue, preventing other vehicles from starting a charge prematurely. In this case, any attempt to charge out of turn might trigger a “Stall reserved for next vehicle in line” message.
This method would provide a straightforward solution—only the next vehicle in the queue would be able to initiate a session. The queuing process itself could be automated when a vehicle navigates to the Supercharger, factoring in estimated arrival time, or it might require manual enrollment once you arrive.
Tesla may also impose limits on queue validity. If a vehicle leaves the charging area, its position could be automatically forfeited.
Software Solution
In China, Superchargers sometimes include locks that come up from the ground, preventing non-Teslas from parking in these designated Supercharger spots. Up until recently, Tesla users had to open up the Tesla app and choose a stall before the lock would go down and allow them to park. However, with a recent update, this is all done on the vehicle’s screen, where the driver can pick the charging stall and automatically have the lock lower.
We may see a similar implementation, where a driver would choose to add themselves to the Supercharger queue, and their position in line and estimated wait time would then be viewable on the vehicle’s screen.
Reservation Signage
Tesla’s reservation about this new queuing system could be around driver confusion. Superchargers weren’t built with a queue system in mind, meaning that there’s no way to tell whether a stall is reserved for a specific vehicle.
A physical indicator could help owners quickly identify when a Supercharger stall is available for the next vehicle in the queue. Tesla could implement a system similar to grocery store checkout lights, where a change in lighting signals whether a register is open or closed.
For example, the Supercharger post could pulse blue when it’s ready for the next user, with a corresponding message in the vehicle stating, “Use the Supercharger post that is pulsing blue.” This would provide a clear, intuitive way to direct drivers to the correct stall.
Tesla can also display a menu inside a vehicle when it first arrives at a Supercharger, letting the driver know that there’s a wait time and explaining the process and their estimated wait time. It can also prompt the driver to be added to the queue.
Tesla Priority
Another factor to consider is how Tesla will handle non-Tesla vehicles in the queue. One possibility is giving priority access to Tesla owners or those subscribed to the Supercharger membership. This would ensure that Tesla vehicles and paying members receive preferred access at busy Supercharger sites, making the membership more valuable while also incentivizing Tesla ownership—especially as the network expands to other EV brands.
Regardless of whether Tesla introduces priority access, the Supercharger queuing system will be a valuable addition, particularly in high-traffic urban locations and during peak travel seasons. By having an official queue Tesla will create a smoother and more organized charging experience for all users.
