Others - Unused! Mirror-integrated tire pressure sensor

This is a mirror-type air pressure sensor. It's unused, but the box shows signs of age, so I've checked that it powers on. It appears to work without any problems. The air pressure is displayed on the left, and it seems to be able to issue warnings for abnormal air pressure or voltage drops. The instruction manual is in English, so the detailed functions, such as the display content, are unknown. Perfect for those who want to give their mirror a unique function or are looking for a rare item! Please check the condition carefully before purchasing.
