I think the issue is that the light illuminates when you have, essentially, no pressure. I dunno what the exact level is, but the threshold to where it turns on is really low. That's like your TPMS sensor letting you know that you have 0 PSI in your tire, at which point you're already fucked. A gauge allows you to identify a DROP in pressure, but not one so severe that it causes engine problems. To use the TPMS analogy, that's like letting you know that your tire pressure has dropped to 25 PSI, which isn't catastrophic, but gives you a heads up that you might want to look into it before your tire essplodes.
