The Light Sync feature turns Tesla cars into rave caves (videos)

Mid-July, Tesla started the rollout of the 2025.26 OTA software update 2025.26 which bundles the new Light Sync feature.

The 2025.26 and subsequent point releases allow Tesla owners of the new Model 3, Model Y, Model S and Model X to sync their car’s ambient/accent lights with the music.

According to Tesla, the Light Sync feature turns your car into a rave cave night club, especially in the dark. Some Tesla owners who tried this feature with different music shared their videos on Elon Musk’s social media platform X (videos below).

As of this writing, 2025.26.4 is the most widely rolled out Tesla update. Around 60% of the global Tesla fleet of cars has installed this subversion point release of the main 2025.26 branch.

After installing the 2025.26 or 2025.26.4 Tesla update, you can access the Light Sync feature by tapping Toybox > Light Sync on your car’s center touchscreen display.

The controls for this feature, shown in the above screenshot, will appear after entering the Light Sync app in your Tesla. You can turn Light Sync On and Off using this UI or enable it only at night.

The Rave Cave option turns on the maximum brightness of the accent lights. Interestingly, you can also match the accent/ambient light color automatically to match the album cover of the song by turning on the ‘Match Album Art Color’ option.

Tesla Launches $0 Down Pre-Owned Leasing for Model 3 and Model Y

Tesla just opened a new door for drivers who want to experience its cars without the heavy upfront cost. For the first time, the automaker is offering leases on certified pre-owned Model 3 and Model Y vehicles in California and Texas. The headline here is simple: zero down payment. That’s right, you can now step into a Tesla with no money upfront, and payments as low as $215 a month.

This is a big shift for Tesla, which has traditionally leaned on straightforward new car sales and leases to drive growth. Leasing used vehicles is rare in the auto industry, since most carmakers and dealers focus on new inventory. By moving into this space, Tesla is signaling just how motivated it is to move cars off the lot before the end of the quarter. As the original report put it,

“Tesla has started offering leases of certified pre-owned cars, which is relatively rare in the industry, with $0 down as it desperately tries to move vehicles before the end of the quarter.”

The timing isn’t random. At the end of September, the $4,000 federal tax credit for used electric vehicles expires. That incentive has been pulling demand forward, with buyers eager to secure savings before the program winds down. Tesla is seizing the moment, offering short and flexible lease terms that make it easier than ever to try out one of its most popular models.

The structure of the leases is designed to be simple. You can choose a 12- or 24-month term, drive up to 15,000 miles per year, and cover your costs with nothing more than the $695 acquisition fee and your first monthly payment. That’s it. No big down payment, no complicated fine print. For many, it’s the most affordable entry point to Tesla ownership that has ever existed. As Electrek summed it up,

“This is undoubtedly the cheapest way to get into a Tesla vehicle right now.”

Behind the scenes, Tesla is dealing with a very real inventory challenge. The company has added more than 50,000 vehicles to its fleet this year alone, and used cars are stacking up as well. Part of the reason is brand perception, some owners rushed to sell their vehicles as Tesla’s reputation took hits connected to its CEO’s political activity. That dynamic, combined with softer global demand, has left Tesla searching for new ways to keep its sales numbers strong.

Globally, Tesla sales are down about 13% this year. While this quarter may see a temporary boost thanks to incentives and new leasing options, many analysts expect sales growth to remain muted for the next 12 to 18 months. The concern is that once the tax credit ends, buyers who miss out may hesitate, leading to a slowdown in EV adoption.

But for buyers, that larger picture isn’t the main story. What matters is that Tesla is suddenly offering an easier, cheaper path into its vehicles. If you’ve been on the fence about driving electric, this is one of the lowest-risk opportunities to test the waters. A short-term lease lets you experience the technology, charging lifestyle, and day-to-day convenience of an EV without locking into a long contract or paying a big sum up front.

This move may be driven by Tesla’s own urgency, but it works out as a win for the consumer. Affordable access, more options, and the chance to drive a Tesla without stretching finances too far, that’s a combination many EV fans have been waiting for. Whether or not it reshapes Tesla’s sales strategy long-term, the opportunity right now is clear: the road into Tesla ownership has never been more wide open.

The engineers guide to battery defects

EV-battery engineers wrestle with defects they can’t see until a pack fails. The Engineer’s Guide to Battery Defects lays out how industrial CT surfaces those threats in minutes. As the paper states, “Industrial CT scanning allows battery engineers to visualize and analyze specific issues related to anodes and cathodes that are otherwise challenging to detect”.

Real-world scans show that “precise 3D imaging reveals the extent and distribution of the anode overhang, enabling…identification of potential areas of concern”, and they spotlight tab-weld voids that can trigger thermal runaway.

With this guide, you’ll come away with practical workflows for R&D, supplier validation, and in-line QA; numeric benchmarks for anode-cathode overhang, porosity, and weld integrity; and a clear blueprint for ISO 26262 evidence packs. The paper explains why regulators insist on catching “delamination, misalignment, or contamination … before they lead to failures in the field” and shows how Voyager dashboards turn those CT measurements into trend data your team can act on.
