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.

Side Note

As a side note the car is highly maintained and runs perfect even when it is cold.
Oil Pan

Thanks for the quick input! I forgot to add a new oil pan was installed about 10,000 miles ago too. So if the mechanic did the job right it should have been cleaned. But perhaps I will make that a weekend project after I upgrade my suspension.
Oil Light

Thank you Ron for the reply. I am going to talk to my mechanic today or tomorrow to see all that was replaced. My mechanic has specialized in Saabs only for about 25 years. I keep all records so I have a mountain of a file. I'll track down that job and let you guys know. Thank you!
Need thicker oil!

The pressure relief was replaced. After that new posting on all "Oil Woes" I suspect I need to use 10W-40 Synthetic now. As for the oil pressure on my car I will have to install an actual oil pressure gauge when I have the money.
