Narrative:

Once on approach to our destination with 900lbs shown on the FMS; we put the gear down and the right main light did not illuminate. We cycled the gear once and the light still did not illuminate. We told the tower we needed to go around. We circled out to the east and the to the west and back around for the runway. During that time we cycled the gear a few more times. We checked the gear horn which; when the gear was down; did not sound. The light was checked and found to be operational. The right light would just not come on when the gear was down. While on the second approach to the runway we made the decision to go around and proceeded to a nearby airport which has a longer runway; better for the wind conditions; and better emergency services just in case. We advised the tower that we need to go to divert and that we had a gear indicator problem and declared an emergency. Once with approach; we advised min fuel; at that time we had around 800lbs of fuel. They vectored us for an approach during which we advised we needed a turn inbound soon. They gave us a turn and priority. We asked tower if they could see the gear to which they responded not at night without a fly by. We told them we did not have the fuel for that. Again no gear horn sounded and we were sure the gear was down we just couldn't verify it was locked by the right main gear annunciator light being out. We set down on the runway with all gear down and rolled off on the taxi way. We landed with around 500lbs and then taxied to the ramp.
