oil pressure gauge to verify you have good oil PSI.
Remove it and put it all in a zip loc bag and keep it, you or someone else will need it one day to diagnose if their alarm
system is bad or if they have low oil PSI.
Rarely do the alarms systems go bad, and it seems most of the times when they do it is they fail to alarm, that is why you listen for the alarm every time before you start the engine, it alarms, you start the engine it and it quits, you have just checked the alarm system
