Narrative:
On final we extended the gear for landing. Had an unsafe gear indication with the left main gear light not illuminated. We communicated to ATC; performed go around and received delayed vectors to work the problem. The red gear unsafe light was not on. We tried a few checks with the airspeed and flaps and rotary test to cross check the gear warning system; and those checks confirmed gear down. We then tried to change the bulb or at least switch the bulb with another to test it. After we switched the bulbs we were unable to re-insert the gear lights and now had no gear indication at all; adding to our problem. We then contacted the assistant chief pilot and discussed the situation and we all agreed to complete the gear extension checklist. We completed the checklist; declared emergency with approach and landed runway 27 and taxied to parking uneventfully. Contacted company afterwords. Suggestions: the only thing I would change with this event is to not mess with the gear lights and contact company right after our pilot checks. Also; I would still feel very uncomfortable landing with a gear light out even after our verification tests checked out.
