## Discrepancy

EMERGENCY CEILING LIGHT FROM SEAT 1-20, 2 LIGHTS OVER THE 2L DOOR, AND FROM SEAT 32-34 ARE ALL INOPERATIVE. AT THE AFT STAIR DOOR THE LIGHTS ARE VERY DIM AND FLICKERING. MAINTENANCE CHANGED B5-101 AND B5-102 BATTERIES OUT OF THE BATTERY POWER SUPPLY, AND REPLACED THE B5-100 POWER SUPPLY. ALL LIGHTS CHECK OPERATIONAL NOW. (LP #4808619)
