Mele Kalikimaka · Tesla Light Show
by Bing Crosby & The Andrews Sisters
Bing Crosby and the Andrews Sisters recorded it in 1950, and it has been the sound of Christmas somewhere warm ever since. The show sways with it: the front and rear turn signals trade cues at an easy, steady pace, working both ends of the car, and the fullest stretch comes in the middle. It sits on the darker side, just under three minutes. A change of scenery between the sleigh bells and the orchestras, and the right pick for a driveway where December means palm trees, or wishing it did.
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. The peak is in the middle third, where roughly 33% of the car is lit against 25% at the top, then it eases back for the finish. If you are filming, the fullest ten seconds start at 1:25, when about 41% of the car is lit at once. Most of the work falls on the front turn signals, re-firing about 0.9 times a second, with the rear turn signals answering back at 0.9. About 55% of the re-firing happens at the rear, so the better view is from behind the car. The quietest part of the car is the side markers, at about 0.4 re-fires a second. It runs 2:55 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 18% of the light values sit at a partial level, so hits are punctuated by fades rather than being pure on and off. Once it starts there is no full blackout at all: at least one light is on the whole way through.

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.
