## Discrepancy

CABIN EMERG LIGHT: THE EMERGENCY LIGHTS IN THE CABIN REMAIN ON WITH THE EMER LT SWITCH IN THE ARM POSITION. AFTER A FEW SECONDS ALL OF THE EMERGENCY LIGHTS FLICKER RAPIDLY. THE ONLY WAY TO GET THEM TO TURN OFF WAS TO SELECT THE EMER LT SWITCH TO OFF.  REMOVED AND REPLACED BATTERY PACKS. IAW EMB505 MM 33-52-01.  OPS CHECK GOOD.
