Wonderful Christmastime · Tesla Light Show
by Paul McCartney
Paul McCartney made it by himself in 1979 with a synthesizer and a lot of good cheer, and that burbling synth riff is a light pattern already written out. The show plays it on the front turn signals with the side markers answering, busy without being frantic, and it genuinely builds, the final third fuller than the first. Mid-brightness, just under four minutes. A cheerful change of texture in a December playlist between the crooners and the rock versions.
How this one is choreographed
This is a busy show. The lights re-fire about 1.0 times a second, near the top of what the catalog runs. It builds. The car runs about 28% of its lights through the opening third and finishes near 35%, so the biggest picture is the one you end on. Most of the work falls on the front turn signals, re-firing about 1.2 times a second, with the side markers answering back at 1.2. It runs 3:48 and averages 69 of 255 across the light channels, a mid-brightness show, with real headroom kept in reserve for the peaks. About 18% of the light values sit at a partial level, so hits are punctuated by fades rather than being pure on and off.
Measured from the exported light sequence for this show, not estimated from the song.
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.
