Narrative:
On final approach immediately after gear extension, no nose gear green or red indicator light was observed. Bad bulb was suspected. Replaced with no indication. After go around the indicator lights and apd (approach progress display) were tested. The nose gear green light stayed illuminated indicating a down and locked condition. Landing was safely executed. Also a visibility inspection, through the viewing window, was conducted.
