Tesla Light Show Generator: Turn Any Song Into a Light Show
7 min read read
Light Show is a Toybox feature that choreographs your Tesla's lights — and, on some models, doors and other closures — to music. Tesla ships a few built-in shows, but the real fun is a custom show set to a song you love. A Tesla light show generator makes that custom show from an MP3 you upload.
What a Light Show Generator Does
A custom show is two files on a USB drive: an audio file (MP3 or WAV) and an .fseq file — a frame-by-frame sequence that tells each light on the car when to switch on and off. Tesla's official guide builds these in xLights, a free desktop sequencer, and recommends a 20 ms frame interval (50 frames per second). Building a show by hand can take a long time, depending on how detailed you make it.
A generator does the sequencing for you: it maps the song's energy across frequency bands onto the car's light channels and exports a ready-to-play .fseq.

Make Your Own Show in 3 Steps
- Upload your song. Sign in to LightMyTesla and upload an MP3.
- Convert. We generate a Pulse show that follows the energy of your track.
- Download. You get a ZIP with a ready-made
LightShowfolder inside: the .fseq and the matching audio, already sharing the same file name — exactly what the car looks for.
New to the file format? Read FSEQ files explained, or follow the step-by-step MP3 conversion guide.
Install the Show on Your Tesla
- Format a USB drive as exFAT, FAT32, MS-DOS FAT (Mac), ext3 or ext4 — NTFS is not supported. Don't keep a TeslaCam folder, map updates or firmware update files on the same drive.
- Create a folder named
LightShow(case-sensitive) at the top level of the drive. - Copy the .fseq and the audio file into it — or just copy the
LightShowfolder from our ZIP. The two files must share the same base name (for exampleshow1.fseqandshow1.mp3). - Plug the drive into a front USB port or the glovebox port, then open Toybox → Light Show → Schedule Show and pick your show.
Park outside and away from public roads before you start, and make sure using Light Show is allowed where you are.
Which Teslas Can Run It?
Model 3, Model Y, Cybertruck, and 2021-or-newer Model S and Model X, on software 2021.44.25 or later. The same show file plays on every supported model; exactly which lights and doors move depends on your model and configuration.
