## Discrepancy

DURING A GROUND INSPECTION, THE EMERGENCY LIGHTS IN THE FRONT HALF OF THE AIRCRAFT STAYED ON WITH THE FLIGHT ATTENDANT’S SWITCH IN THE OFF POSITION AND THE COCKPIT SWITCH IN DISARM.  MAINTENANCE REMOVED AND REPLACED THE EMERGENCY LIGHT POWER SUPPLY, OVERHEAD AT SEATS 1A AND 1B.  OPERATIONAL CHECKS GOOD.  AIRCRAFT OK FOR SERVICE.  (K)
