Aircraft
Descending on approach PF (Pilot Flying) called for gear down before landing checklist; I complied with the command; placed the gear lever down; and accomplished the checklist to the item Gear down - 3 green/verified. At this time I noted that the gear down and locked annunciation for the left main landing gear was not illuminated but the gear unsafe light was extinguished. I notified the PF and we elected to recycle the landing gear handle. The gear annunciator remained in the same condition when recycled. We advised Tower of a need to conduct a missed approach to run a checklist and requested that they observe the landing gear position during a low approach which they granted. Approximately 300 feet before above TDZE (Touchdown Zone Elevation) the landing gear annunciator became illuminated. This change was noted and I requested landing clearance from the Tower; informing them of the updated circumstances. Landing was continued and uneventful.Noted during checklist itemFailed connection for landing gear bulb causing failure to illuminateAs we were descending below 1500 ft. I delayed checklist usage. I recycled the landing gear as a technique from training and requested the low flyby from Tower to assist in troubleshooting gear position. When the landing gear annunciator illuminated I requested landing to prevent further incidents from occurring during a prolonged flight.
