Question How safe driving with oil light on?

Yesterday my oil light came on while on the highway. Oil level is OK and no leaks apparent. At first the light would be off during idle. It would come on between 1000 and 2000 RPM, and go out again right about 2100 RPM.

A very helpful person on this forum indicated that I must have the pressure mechanically checked, and indicated 3 current possibilities: (1) Bad Sending Unit (2) Weak Pump (3) Excessive Bearing Clearance.

My question is:
How safe am going to be driving this temporarily? I drove over 60 miles yesterday after this started (heavy rain with wife and daughter in tow). It seemed OK, but I'm worried I'm causing damage. This is my only mode of transportation, and I have to take this car in for body work as soon as I receive a check for body repair/rental from the insurance of the person who rear-ended me. With any luck, I could get this worked on at the same time.

That's impossible to tell for sure.

That's what the mechanical pressure reading was supposed to determine.

If it's your sending unit then chances are you're fine. But if the oil pressure is actually too low then you're going to have trouble soon.

What make of car? Engine size? Mileage? Sending units are cheap--engine rebuilts are not--replace the unit, or have the oil pressure checked with a guage.
