Narrative:
Extended landing gear on approach to ZZZ. Nose gear lights dark (no green). Nose lights don't test. Missed approach; advised ZZZ; ran QRH. Several other gear lights inoperative on gear light cluster but only nose with all inoperative. QRH suggested a light problem; phone patch with maintenance control agreed. Dispatch and I decided to use all available help; advised ZZZ to roll crash fire rescue equipment. Planned landing procedures for nose not extended as back up. Replaced both nose gear green bulbs. Lights tested. Extended gear; all green. Advised ATC crash fire rescue equipment not required. Reviewed landing with nose gear not extended. Landed normally. Made maintenance log entry.
