But I will pick up a oil pressure gauge and go from there
It's worth checking for peace of mind if nothing else. Hey, you'll get to learn a little bit about what's going on under your hood, too.
You've gotten a lot of scary responses here, but with good reason. Let me put it into a little perspective for you: I've owned an 02 wrx for several years, and i've never seen my oil light come on (except for cranking). The consensus is that if the oil light actually comes on, it's not a warning but an indication that something catastrophic has occurred that will likely cost $Texas.
Behind all of the replies that may come off harsh are people that have wanted your car to be in working order.
Hopefully it was something to do with condensation as previously mentioned and you have nothing to worry about.
