A turboprop commuter aircraft was unable to get safe gear indications and requested a flyby of the tower for a visual confirmation of the landing gear status. In attempting to manage the emergency request while maintaining traffic flow and separation the local controller cleared a B737 to luaw on the runway about to be utilized for the flyby inspection. Due to taxiway closures and outbound traffic the controller was unable to get the jet off the runway prior to the flyby and a facility asde-X alarm was triggered as the commuter aircraft passed overhead.

Narrative:
On a circling approach to the runway when the gear was selected down; the green nose gear safe indicator light failed to illuminate. We executed a go around and notified ATC who gave us runway heading and an altitude. We ran the gear unsafe checklist then contacted dispatch and advised we were going to go below divert fuel but had determined our most suitable airport. We then declared an emergency and performed a low approach to verify gear down and locked by tower; who did confirm the gear was down. ATC then re-circled us for an approach and normal landing.
