## Discrepancy

LAV SMOKE DETECT LIGHT ILLUMINATED IN FLIGHT.  FLIGHT CREW INVESTIGATED AND DID NOT SMELL SMOKE.  AIRCRAFT LANDED UNEVENTFULLY.  MAINTENANCE INVESTIGATED AND COULD NOT DETERMINE SOURCE.  IT WAS NOTICED THAT THE LAV OVERHEAD LIGHT FLICKERED INTERMITTANTLY WHEN THE LAV DOOR WAS CLOSED.  HOWEVER, THE LIGHT DID NOT EMIT SMOKE.  LAMP WAS REPLACED ANYWAY AND NO FURTHER PROBLEMS NOTED WITH SYSTEM.  SYSTEM TESTS WERE NORMAL.
