## Discrepancy

FLIGHT CREW CONFIRMED THAT THE EMERGENCY LIGHT SYSTEM DID NOT ILLUMINATE ANY LIGHTS WHEN TESTED AND WAS INOPERATIVE WITH THE SWITCH IN ARM AND ONLY GROUND POWER AS A SOURCE DURING INITIAL POWER-UP.  MAINTENANCE REPLACED ALL EMERGENCY LIGHT BATTERY PACKS AND THE SYSTEM RETURNED TO AN OPERATIONAL CONDITION.
