Narrative:

4TH day of a very long and grueling 4 day trip. During taxi into ramp after landing, while completing checklist, I discovered seat belt and sterile cockpit cabin signs switched off. Flight attendant advised they came on during the descent and shortly before landing were turned off. I believe captain accidentally turned both cabin signs off while activating the landing lights. Cause -- fatigue!!
