At what PSI does the warning light come on?

I’m a bit OCD about tire pressure and check it almost every time I drive and I was wondering how low it has to get to trigger the warning. Has anyone seen the warning when they didn’t have a flat tire?

I have the 19s, which are supposed to be at 49 PSI. When I swapped out to snow tires, the people who put them on didn't inflate properly. The warning came up. All four were either 42 or 41 PSI.

I also have the 19’s. Thanks.
