Narrative:

Our cessna 152 was flying from troutdale (ttd) to the aurora state (3s2) airport. We had flight following from portland approach and received several TA's. Before we terminated flight following with pdx departure the controller told us about a lower flying aircraft about 4 mi away. At this point we were about 5 mi north at aurora state and had that traffic in sight (no factor). We then proceeded to finish the before landing and descent checklist and my student called aurora unicom. We were still level at 2500 ft MSL. Suddenly the landing gear and belly of another C-152 or 172 filled the windshield. This aircraft was heading west and descended through our altitude. We had no time to react nor to get the tail number. This aircraft had no navigation lights on, the pilot was neither on pdx departure frequency nor on aurora unicom frequency. Lights-on, transponder-on, use frequencys, look for traffic, always!
