Narrative:
On walkaround; noticed that the down lock inspection light for the nose gear was inoperative. Notified maintenance. Maintenance opted to defer due to time constraint. This light must work to view the down lock stripe through view finder from cockpit! (I.e.; no-go light (I remember it being a no-go item from yrs ago). Maintenance response; 'well; the computer took it so we can defer it.' unacceptable! We waited until light fixed then continued our day. Worst thing is the notification occurred over 30 mins prior to scheduled push. Had we simply re-lamped aircraft; we would have left on time. As was; we left 18 mins late.
