For Whom the Bell Tolls · Tesla Light Show
by Metallica
Cliff Burton's distorted bass intro, the tolling bell, and a slow, enormous riff from Ride the Lightning in 1984. The show is slow and enormous too: the tail lights lead with the front turn signals answering about once every two seconds, each cue landing on its own. Only about a tenth of the values are partial, so it is hard on and hard off, and it runs very bright. The first two thirds carry the most light before the close eases. Five minutes eleven. It joins Enter Sandman and Master of Puppets for a full Metallica set.
How this one is choreographed
The choreography is deliberately unhurried: the lights re-fire about 0.4 times a second, so cues land as separate moments rather than a blur. The peak is in the middle third, where roughly 40% 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 0:08 with about 40% of the car lit, so have people watching from the first bar. Most of the work falls on the tail lights, re-firing about 0.5 times a second, with the front turn signals answering back at 0.5. The work is split close to evenly between the two ends, 54% front to 46% 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 0.2 re-fires a second. It runs 5:11 and averages 92 of 255 across the light channels, a bright show that stays close to full through its busiest passages. The values are mostly hard on or hard off, only about 10% of samples sitting at a partial level, which reads sharp and percussive from across a parking lot. The longest full blackout lasts 1.1 seconds, at 5:05, and that pause is what makes the next hit land.

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.
