## Discrepancy

EMERG EXIT SIGN/LIGHT: THE EMERGENCY EXIT SIGN LIGHT OVER PASSENGER ENTERY DOOR REMAINS ON EVEN AFTER TURNING THEM OFF. PER MAINTENCE, I RESET THE G SWITCH YESTERDAY AND THEN AGAIN TODAY HAD THE SAME ISSUE. RESETTING THE G SWITCH DOES TURN OFF THE LIGHT. CORRECTIVE ACTION: PERFORMED EMERGENCY LIGHTING OPERATIONAL CHECK. OPERATIONAL CHECK GOOD. NO FAULTS NOTED. CE-680A MM 33-50-00
