I'll go along with Joe.

The reasoning is that the way your light is operating is one of its warning modes. It will exhibit that activity when it has seen a non airbag related safety issue. It continues to allow the bag operation though probably at a different crash profile.

The typical problem that is not airbag related is the belt buckles and they fail regularly.
