Changed for conventional to full synthetic, dummy light problem
I just changed over from a conventional oil to Mobil 1's new High mileage Full Synthetic. Now I get the low oil dummy light all the time. I checked the dipstick and I've got the right amount in there as well as good oil pressure. I can't seem to find any leaks either so I'm assuming that the computer just isn't reading the oil level correctly because its a synthetic? I used a 10w-30 and the car is a 96GT if that matters. This happened to anyone else?

Oil level has nothing to do with what kind of oil it is. Most cars don't have the oil level switch hooked up to the computer either, it usually goes right to the dash. I'm guessing this is unrelated to the oil change; did this happen immediately after you changed the oil and started the engine?

Switch might be loose, might be going bad, or might have a connector or wiring problem. Those are the obvious choices. Where is the switch in relation to the filter, etc.? Any chance something light have got knocked loose during the oil change?
