Don't You Worry Child · Tesla Light Show
by Swedish House Mafia ft. John Martin
Swedish House Mafia's farewell record, built as one long lift, and the show goes with it: it genuinely builds, finishing wider than it opens, so the last minute is where the whole thing has been heading all along. An even pace keeps that climb readable rather than frantic, with the signature bar leading and the tail lights underneath. Three and a half minutes. This is the other New Year's option alongside Firework and the calmer of the two, worth running earlier in the evening: it swells where Firework detonates.
How this one is choreographed
The lights re-fire about 0.7 times a second, a middle pace that tracks the beat without crowding it. It builds. The car runs about 30% of its lights through the opening third and finishes near 37%, so the biggest picture is the one you end on. If you are filming, the fullest ten seconds start at 1:07, when about 43% of the car is lit at once. Most of the work falls on the signature light bar and daytime running lights, re-firing about 0.9 times a second, with the tail lights answering back at 0.8. The work is split close to evenly between the two ends, 50% front to 50% rear, so it plays from either end, or side-on from the curb. The quietest part of the car is the inner main beams, at about 0.4 re-fires a second. It runs 3:33 and averages 78 of 255 across the light channels, a mid-brightness show, with real headroom kept in reserve for the peaks. The values are mostly hard on or hard off, only about 13% of samples sitting at a partial level, which reads sharp and percussive from across a parking lot. The longest full blackout lasts 1.9 seconds, just before the close, and that pause is what makes the next hit land.

Get it for your Tesla
This show downloads for every Tesla: Model 3, Model Y, Model S, Model X, and Cybertruck. Preview it on your model with the View-on picker above, add it to your library, and it re-tailors to your car's lights automatically.
How to play it on your car
- Open the show above and add it to your library (remix it in the builder first if you want).
- Add your own copy of the song: an MP3/WAV you own. We distribute only the light pattern, never audio.
- Export the
.fseqbuilt for your model, then place your song next to it (or let the one-click USB writer do both). - Put both files in a
LightShowfolder on a USB drive. Or skip the manual steps: in Chrome/Edge, click 🔌 Write it to my USB drive for me right after exporting and we do it all, verified byte-for-byte. Then plug in and start it from Toybox → Light Show. Full walkthrough in the setup guide.
Car says Light Show instead of Custom Light Show, or the drive is not detected at all? That is the USB format, the folder name, or filenames that do not match. If it plays but drifts out of time, that is the audio sample rate. Fix both here.
