Narrative:

The flight was from ftw to teb along route ftw.DALL5.txk.J42.gve.METRO4.teb. The flight was uneventful until we were handed off to ZNY and were vectored for the ILS 6 approach to teb. We completed the normal approach checklist. When established on the approach (localizer captured/GS approximately captured) and approximately 6 mi from teb, we selected the landing gear down and completed the before landing checklist, and then noticed that we only had the nose, and right main gear down lights, and not the left main gear light. We then tested the cockpit lights and found all gear lights to be good. We elected to cycle the gear back up and down again, with the same result (no left main gear down light). We were then handed off to teb tower where we requested a low approach only, and that the tower take a visual look at our left main gear to determine its status. The tower said the left main gear appeared to be down and told us to contact new york approach again. Thereafter we requested another ILS 6 into teb from new york approach. When new york approach handed us back to teb tower, we requested that the equipment be standing by and were cleared to land. We made a normal uneventful landing. Thereafter we taxied to the FBO (yxvx zwz) to disembark our passenger and get our landing gear looked at by maintenance. (They found a loose electrical connection (cannon plug). We followed all FARS and complied with all manufacturer's (gulfstream) procedures. Because we did, in fact, declare an emergency, I felt that I had better submit this NASA report.

Title: A GULFSTREAM II ON FINAL APCH AT 1500 FT DECLARED AN EMER DUE TO AN UNSAFE WARNING ON THE L MAIN GEAR CAUSED BY ELECTRICAL CONNECTOR.

Narrative: THE FLT WAS FROM FTW TO TEB ALONG RTE FTW.DALL5.TXK.J42.GVE.METRO4.TEB. THE FLT WAS UNEVENTFUL UNTIL WE WERE HANDED OFF TO ZNY AND WERE VECTORED FOR THE ILS 6 APCH TO TEB. WE COMPLETED THE NORMAL APCH CHKLIST. WHEN ESTABLISHED ON THE APCH (LOC CAPTURED/GS APPROX CAPTURED) AND APPROX 6 MI FROM TEB, WE SELECTED THE LNDG GEAR DOWN AND COMPLETED THE BEFORE LNDG CHKLIST, AND THEN NOTICED THAT WE ONLY HAD THE NOSE, AND R MAIN GEAR DOWN LIGHTS, AND NOT THE L MAIN GEAR LIGHT.
