Narrative:

After landing at iah runway 27; ground initially gave us incomplete instructions to taxi to the ramp. Our instructions ended at taxiway RA; when we approached taxiway wb; the first officer queried ground to ensure that we should taxi wb to wh to the ramp. As we taxied south on wb; we were looking for the ramp and taxiway wh. We never saw a sign for wh; but I recognized the ramp 10 feet after we passed the taxiway. I immediately stopped the aircraft. When we talked to ground; he apologized that the lights were out on the signage; but thought we were familiar. We eventually taxied further down to turn around to the ramp.[caused by] no NOTAM for the inoperative lighting on the signage and my own fatigue from several circadian rhythm changes in the proceeding 3 days.
