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.
