Sleigh Ride · Tesla Light Show
by The Ronettes
The Wall of Sound, rebuilt in light: layers stack the way the record does, castanets and bells flicker across the signals, and every "ring-a-ling-a-ling-a-ding-dong-ding" bounces the full front. Leroy Anderson wrote the tune in 1948 with no Christmas in it whatsoever, and the words were added two years later. Brightness runs near the top of the catalog and the pace stays even, so it holds a street without ever turning frantic. Signature-bar led, three minutes even. Sixty years on, still the warmest thing in the Christmas lineup.
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. The peak is in the middle third, where roughly 43% of the car is lit against 39% at the top, then it eases back for the finish. The fullest ten seconds come early, starting at 0:14 with about 43% of the car lit, so have people watching from the first bar. Most of the work falls on the tail lights, re-firing about 1.1 times a second, with the side markers answering back at 1.0. The work is split close to evenly between the two ends, 47% front to 53% rear, so it plays from either end, or side-on from the curb. The quietest part of the car is the front turn signals, at about 0.8 re-fires a second. It runs 3:02 and averages 91 of 255 across the light channels, a bright show that stays close to full through its busiest passages. About 17% of the light values sit at a partial level, so hits are punctuated by fades rather than being pure on and off. It never goes completely dark for long: the longest gap is 0.6 of a second, just before the close.

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.
