Narrative:
Selecting gear down on approach; received no primary or secondary landing gear down indications. Had normal gear door/lowering sounds. Executed go-around; raised gear again with no gear indications whatsoever. Without an applicable QRH procedure I (first officer) found 'ldg gear warn pri' circuit breaker popped. Captain used his emergency authority and directed reset due to our low fuel state (2000 pounds above minimum). Upon lowering gear circuit breaker popped again and captain again directed a reset. This time circuit breaker stayed in and all pri and second gear indications were normal green. Uneventful landing followed.
