Narrative:
Did not get green lights indicating gear down and locked. Executed missed approach and performed flight manual procedure. During troubleshooting; I reset landing gear circuit breaker which was popped on circuit breaker panel. Indications returned to normal; and we executed a normal approach and landing. Originally had declared emergency during initial troubleshooting because it did not appear we were going to get the proper indications and would have to verify the gear down visually. After indications to normal; however; I canceled the emergency with ATC and landed normally.
