Oil Light Flickers at Normal Operating Temps

Greetings Saab enthusiast,
I have been driving Saab's for five years now and have owned two so far. The first a 1995 NG 900S 2.3L and a 1999 Saab 9-3 SE T5 management (have owned for two years).
About 9 months ago my oil light began flickering after the car was at normal operating temperature and at idle. I don't do a whole lot of driving (about 15 miles a day) so my engine doesn't always arrive to the normal operating temperature. But when I do, after a while of driving the light flickers. This happens faster as the outside temperature heats up. Today this happened and managed to get home. I left the car on while the oil light flickered and the chime going off so I could check the engine. The engine was running perfect even though the oil light came on.
Can anyone give me some insight or have the same problem occurring? I am very meticulous and below is a relative list of replaced parts.

Replaced & checked parts:
1. Oil pump and seals
2. Oil changed EVERY 3000 miles with Quaker State full syn. 10W-30 along with oil filter
3. Oil pressure switch
4. Checked and cleaned PCV check valve & PCV nipple
5. Cleaned IAC valve
6. Lightly cleaned throttle body

Thanks for any input guys. And I will be posting a video soon on youtube to show the issue.

10w30 is too thin....bump it up to 40wt and watch your light go away.......sounds like it might be time to drop your pan and clean the screen.
well if its a new pan, I would just say get a thicker oil.......the general consensus is that 30wt is way too thin.
