With 220K on the motor, I have to say the motor is just plain getting tired. Oil pumps do wear and don't pump like when they were new, but bearings will wear faster. You could remove the oil pressure sending unit and screw in a regular oil gauge to test pressure, but you will probably find the light is telling the truth. You could go to a heavier oil, but if I'm correct, your on borrowed time. Hope this helps.
