Run Rudolph Run · Tesla Light Show
by Chuck Berry
Chuck Berry guitar, Christmas lyrics, no compromise on either: the riff drives the front of the car at rock-and-roll tempo, the piano rolls bounce underneath, and the whole body kicks on every chorus. It moves at a genuine rock-and-roll clip and is gone in two minutes and forty-five seconds, tail-led, peaking through the middle. Berry recorded it in 1958 and clearly saw no reason to slow down for the occasion. The show for people who like their Christmas with some horsepower, and a good palate cleanser after a ballad.
How this one is choreographed
This is one of the fastest shows in the library: the lights re-fire about 1.2 times a second and rarely sit still. The peak is in the middle third, where roughly 35% of the car is lit against 32% at the top, then it eases back for the finish. If you are filming, the fullest ten seconds start at 1:17, when about 41% of the car is lit at once. Most of the work falls on the tail lights, re-firing about 1.4 times a second, with the front turn signals answering back at 1.4. 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 rear turn signals, at about 1.1 re-fires a second. It runs 2:45 and averages 76 of 255 across the light channels, a mid-brightness show, with real headroom kept in reserve for the peaks. 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 0.7 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.
