Hansshow uploaded two new sets of firmware for Ultra Mini Screen Display to their web site at
Mini Tesla Model 3/Y Gauge Cluster Screen|LCD Display|Hansshow. See screenshot below:

First (#1) firmware fixed the parking, low/high beam head lights status indicators. Unzip both zip and rar files. Hansshow accidentally included two files of IDENTICAL file names,
can_app.bin, but with different dates. The one you want was dated November 16, 2022 (not October 17, 2022). The other necessary file is
app.upd. This is very IMPORTANT. After finishing downloading to your device, in the Settings setup screen, set the
"CAN" option to 2 (at lower left) which is designed for lights status indicators. Load this firmware into your device first before going to #2 in next paragraph. Please see video tutorial. See post number 46 of this thread for clearer instructions. That post uses exact same firmware as the link from Hansshow. Also see post number 66 of this thread for description and pictures of new lights status indicators.
Second (#2) firmware update is called "Plaid mode" and it's kind of a gimmick but also kind of fun. This update also introduced 12 Hour clock format which is nice for USA. Note that there's only one firmware file,
app.upd, for this firmware update. You won't see
can_app.bin and it's not needed. See video tutorial.
I've tested both firmware updates and they work well. Let me know if you have questions or trouble updating the firmware to your Ultra Mini Screen Display device.
If you have not yet updated the headlights status indicator bug fix, I suggest to download this firmware update first and then the "Plaid mode" firmware update so that you will have both updates as described above. If you only updated the "Plaid mode" firmware and not the headlights status indicator bug fix, you may not get headlights status indicator bug fix.

Good luck.
