Narrative:

When extending the landing gear, crew noticed we did not have 3 green gear lights, so we cycled the landing gear but we still had no lights so we notified the tower of our problem and as we flew by the tower, they said our landing gear all appeared to be in the down position. Also we cycled the gear up and they said they saw it retract. The tower then gave us clearance to 3000 ft and permission to stay in the air traffic area to try to fix our problem. We ran the emergency checklist. After that, we jiggled the gear handle and all 3 green lights came on so we notified the tower and went in to land. Upon landing, the crew called and notified operations and maintenance of our problem. Maintenance explained what probably caused this situation and said that nothing needed to be inspected and we could continue the flight.
