## Discrepancy

DID NOT RECEIVE A LEFT MAIN LANDING GEAR INDICATION WHEN LANDING GEAR SELECTED DOWN. CYCLED LANDING GEAR UP AND BACK DOWN.  LEFT MAIN STILL DID NOT SHOW A DOWN INDICATION. WHILE WORKING THROUGH THE LANDING GEAR EMERGENCY EXTENSION CHECKLIST, LEFT MAIN INDICATION BEGAN TO FLICKER AND THEN REMAINED ILLUMINATED.
