Infotainment settings...lighting setting question

:
2017 Mazda CX-9 Grand Touring
Hello all. I'm wondering, in the "Settings", "Vehicle", "Lighting" settings. What does the "Light On Vol" setting do? I've changed it from High, Low and Off but don't notice anything changing. Does anyone know what this lighting setting does??
 
Man, this forum is slow.

Yes, the alarm setting will only really work if you DON'T have the lights set to come on after the car goes off.

Yes...this is confusing, especially since it isn't explicitly mentioned in the manual. This setting basically controls the beeping sounds the car makes if you leave the lights on while the car is off.
