Narrative:
On approach to landing runway 29 at bed, we observed 3 green and no red lights indicating gear was down and safe. On short final, the right main green gear light went out, but had no red. Cycled gear and went around allowing tower to visually check gear down and landing light on confirming gear down and locked. After cycling gear, we got all 3 green and locked -- tower called out emergency equipment for safety sake. Made landing with no incident, then ran ground checks which checked good. Then called maintenance. They confirmed it was safe to operate and that it was probably a faulty microswitch, brought to maintenance and had repaired.
