It's Beginning to Look a Lot Like Christmas · Tesla Light Show
by Michael Bublé
Meredith Willson wrote it in 1951 and Michael Bublé made it his own in 2011: big band swing with sleigh bells on top. The show keeps it elegant, the side markers leading around the body at an unhurried pace with the rear turn signals answering, and the light sits on the gentler, darker side of the catalog. The fullest stretch arrives in the middle, when the horns open up. Three minutes twenty-seven. The right pick for a dinner party where the car is decoration rather than the main event.
How this one is choreographed
The choreography is deliberately unhurried: the lights re-fire about 0.6 times a second, so cues land as separate moments rather than a blur. The peak is in the middle third, where roughly 32% of the car is lit against 25% at the top, then it eases back for the finish. Most of the work falls on the side markers, re-firing about 0.7 times a second, with the rear turn signals answering back at 0.7. It runs 3:27 and averages 61 of 255 across the light channels, a darker show that spends most of its time well below full, so the hits carry further. About 17% 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.
