When I extended the landing gear on visual approach for Runway 33R I observed the right main landing gear down light was not illuminated. I executed a missed approach and advised Tower of the situation. I requested delay vectors while I troubleshot the problem using the aircraft's QRH. I also contacted Company Operations and notified them of the issue. Once established on delay vectors I used the QRH Abnormal Checklist entitled 'Changing Landing Gear Indicator Light Bulb'. After the checklist was complete the right main landing gear down lock light was still not illuminated. I continued with the QRH Abnormal Checklist entitled 'Landing Gear Will Not Extend Hydraulically'. As part of the procedure the landing gear was extended using nitrogen or 'blown down'. Finally I did a low approach over 33R while Tower looked at my landing gear. Tower confirmed that all of the landing gear appeared to be down. I consulted with base Maintenance and they agreed with the procedures I had done and had nothing else to recommend. I notified the passengers of the emergency extension of the landing gear; which the gear appeared to be down; and we would be landing shortly. I executed a normal landing; all landing gear remained down and locked; and I cleared the runway. I wrote up the landing gear discrepancy in the aircraft logbook and called our company Maintenance Control.
When the right main landing gear safe light failed to illuminate the pilot of a C-402 executed a missed approach; accomplished the associated QRH checklists; did a fly-by with the Tower for a visual inspection and ultimately landed safely despite the light remaining extinguished.
