## Discrepancy

EMERGENCY LIGHTS OVER THE LAV AND BY YOUR FEET ON THE LAV AND THE EXIT SIGN BEHIND SEAT 7 FAILED PREFLIGHT TEST (ARMED AND BATTERIES OFF). PERFORMED QRH PROCEDURE (CHARGED TWICE) AND THEY STILL FAILED. IN THE "ON" POSITION, NO EMERGENCY LIGHTS ILLUMINATED. CORRECTIVE ACTION: REPLACED FUSE. OPS CHECK GOOD. IAW CE-680A AMM 33-50-06 AND TC-FLT-33-1001.
