Narrative:

On final approach into charlotte, the landing gear was extended and we experienced a failure of the green downlock indicators. We advised the tower that we would need to go around and troubleshoot the problem. We recycled the gear, and switched and tested the bulbs with the failure remaining. The alternate gear extension procedure was followed, resulting in secondary indications the gear was down and locked. We requested the emergency equipment, briefed the passenger, and landed without incident. On rollout we advised the tower that we could taxi to the ramp and that we no longer needed the emergency equipment. Upon reaching the ramp the mechanics pinned the gear and the passenger were deplaned.
