The airbag light on the dash comes on and off.

What is your question?

A few days ago the airbag icon between the gauges would light with a bell sound, and then go off. I timed them and it took anywhere from 30 seconds to 2 minutes before it came back on, but no regular pattern. I didn't not notice any consistent driving condition (bumps, acceleration, braking). Yesterday it stayed on most of the day.
