## Discrepancy

FUEL CROSSFEED VALVE LIGHT ILLUMINATED INTERMITTENTLY DURING FLIGHT WITHOUT SELECTING THE OPEN POSITION.  WHEN THE LIGHT IS ILLUMINATED, IT IS IN THE BRIGHT MODE. LIGHT CYCLES FROM BRIGHT TO OFF THROUGHOUT THE FLIGHT.  ACFT GROUNDED.  INBOUND CREW REPORTS FUEL BURN NORMAL.  VALVE OPERATION NORMAL IAW AMM 28-22-21.  INSPECTED VALVE & CONNECTOR.  ALL CHECKS GOOD. VISUALLY CONFIRMED VALVE OPERATION.  OK FOR SVC.
