Narrative:
The flight was uneventful until the gear was extended just outside ruett (OM). At that time, we noticed that the left main gear down (green) light was not illuminated. We requested to miss the approach. We climbed to 2500 ft MSL and attempted to cycle the gear again. The result was the same -- the left main gear door (green) light did not illuminate. The gear disagree checklist was accomplished on land, page 6. We tried several times to establish communications with dfw dispatch, and airline tech via commercial radio. However, all attempts failed. Finally bwi operations relayed the message from dfw dispatch that land, page 6, were the correct procedures to follow. We accomplished a low level fly- by in which the left main gear was confirmed in the down position. Landing was successful. Maintenance inspected left main gear assembly before we taxied to the gate.

Title: CHKLIST USE AND A LOW FLY-BY THE CTL TWR IS NEEDED TO CONFIRM A B757-200 L MAIN GEAR IS IN THE DOWN POS.
Narrative: THE FLT WAS UNEVENTFUL UNTIL THE GEAR WAS EXTENDED JUST OUTSIDE RUETT (OM). AT THAT TIME, WE NOTICED THAT THE L MAIN GEAR DOWN (GREEN) LIGHT WAS NOT ILLUMINATED. WE REQUESTED TO MISS THE APCH. WE CLBED TO 2500 FT MSL AND ATTEMPTED TO CYCLE THE GEAR AGAIN. THE RESULT WAS THE SAME -- THE L MAIN GEAR DOOR (GREEN) LIGHT DID NOT ILLUMINATE. THE GEAR DISAGREE CHKLIST WAS ACCOMPLISHED ON LAND, PAGE 6. WE TRIED SEVERAL TIMES TO ESTABLISH COMS WITH DFW DISPATCH, AND AIRLINE TECH VIA COMMERCIAL RADIO. HOWEVER, ALL ATTEMPTS FAILED. FINALLY BWI OPS RELAYED THE MESSAGE FROM DFW DISPATCH THAT LAND, PAGE 6, WERE THE CORRECT PROCS TO FOLLOW. WE ACCOMPLISHED A LOW LEVEL FLY- BY IN WHICH THE L MAIN GEAR WAS CONFIRMED IN THE DOWN POS. LNDG WAS SUCCESSFUL. MAINT INSPECTED L MAIN GEAR ASSEMBLY BEFORE WE TAXIED TO THE GATE.
