Narrative:

Gear down and locked annunciator failed to illuminate. We attempted to change annunciators to verify burned out bulb. As a result, all 3 annunciators failed. Horn system and gear in transit light indicated gear down and locked. As a precaution, we declared an emergency and diverted to pit. I performed a manual extension of the gear. We landed without incident and taxied in to gate. We deplaned our passenger and had gear pinned as soon as maintenance could arrive. Supplemental information from acn 519567: we landed with no incident. Then the captain taxied to the gate with no incident and the passenger were deplaned with no injuries.
