Since it's Saturday right now in China, I'm probably not going to get latest and greatest firmware updates for Hansshow Mini Screen Display until Monday (China date/time).
If you want me to include latest firmware updates with headlights status indicators fixes but still has minor 12H/24H clock bug, I can include necessary firmware files and a simple video instructions right now, let me know. So far it's been working well and stable but I will not be responsible for any damage to your Hansshow Mini Screen Display but that's unlikely to happen.
Here's is what the new setup screen looks like. Notice "CAN" option set to "2" dedicated to this firmware upgrade. Also notice 12H/24H clock format setting:
