## Discrepancy

SEARCHLIGHT WAS REMOVED FROM ANOTHER ACFT AND SENT IN FOR REPAIR TO CORRECT A ''STUCK ON - LIGHT WILL NOT TURN OFF" PROBLEM.  UNIT WAS REPAIRED AND INSTALLED ON N127LN, 7 HOURS PRIOR TO THIS FAILURE EVENT FOR THE SAME PROBLEM -  LIGHT IS STUCK IN THE "ON" POSITION AND WILL NOT EXTINGUISH WITH THE SWITCH.  SWITCH WAS TROUBLESHOT AND FOUND TO FUNCTION PROPERLY.
