Narrative:
As we approached the airport we were vectored for an ILS. The captain called for; and I executed; the approach checklist. As we continued down the ILS he called for gear down and flaps twenty. I positioned the switches and gear and flaps began to transit as normal. During the before landing checklist the captain first noticed that we had only two green lights lit on the position indicator. The nose and left main indicated down and locked. The right main light did not illuminate. The red lights in the gear handle were not illuminated. I confirmed that we only had two green lights.the captain called for and began a go around while I began the missed approach checklist. We both agreed that we should not raise the gear at that time. I informed the tower about the go around and we were instructed to enter a left downwind and asked what our intentions were. I told them that we had only two lights and we need a few minutes for troubleshooting. Both tower and an airliner crew holding short commented that the gear appeared to be down and locked.we executed the abnormal procedure for gear light indications. The check list had us verify that the red up lock handle light was extinguished and that no gear horn sounded when flaps were past twenty degrees and throttles retarded. The checklist instructed us to land normally. Both the captain and I agreed that all three gear were down and locked and that the problem was with the bulb inside the position indicator. We were vectored for the ILS once again and landed uneventfully.I believe that captain and I worked well together as a crew. Every decision was made with both his and my input. We followed the checklist and resolved the issue quickly and efficiently. In hindsight; we should have taken advantage of the offer to position emergency equipment. We were both confident that it was only an indication issue and not an actual gear issue so we decided to decline emergency services.
