Narrative:

We were cleared for the visual approach. On about a 5 to 7 mile final while conducting the before landing checklist; the landing gear handle was moved to the 'down' position. After the landing gear was finished cycling; it was noted that the right main landing gear 'down' light was not illuminated. The landing gear was recycled; and again the right main landing gear 'down' light did not illuminate. I notified tower that we were not receiving an indication that our right main landing gear was down and locked and that we would like to do a low approach and have them look to see if they saw all three landing gear down and the landing lights on. After the low approach; we were informed by the tower that they could see all three landing gear and the main landing gear lights were on; and then asked what we would like to do. I informed the tower we were running our checklists but would like to stay in the pattern while we conducted the checklists. We were then asked by the tower if we would like the fire trucks standing by when we made our landing; which I replied 'sure'. After discussing the situation in the cockpit; it was the conclusion of both pilots that the light bulb was most likely burnt out and the landing gear was indeed down and locked; and a normal landing should be made. However; just to make sure the landing gear was actually down and to avoid any problems; the emergency landing gear extension checklist was run and the landing gear was 'blown down' using the nitrogen bottle. The landing was made normally; and after landing; the fire trucks pulled up next to the aircraft to inspect it and verify that everything was ok. After we relayed everything was fine; they drove off and the airplane was taxied the FBO where service was then set up by the director of maintenance. The aircraft was serviced and flown home the next day without incident.
