## Discrepancy

THE EMERGENCY LIGHT SWITCH AT THE ATTENDANT PANEL IS INOPERATIVE.  LIGHTS WILL NOT TURN ON WHEN SWITCHED TO ARM (ON).  TROUBLE SHOT PER B717 SDS 33-51-00-003 & WDM 33-51-11 AND SUSPECT B5-125 BATTERY PACK.  REPLACED THE OVERWING EMERGENCY EVACUATION BATTERY PACK PER B717 AMM 33-51 AND NOW THE OPERATIONAL CHECK IS GOOD.
