## Discrepancy

THE EMER LIGHTS DO NOT ILLUMINATE WHEN PLACED IN THE ON POSITION.  WE RAN THE QRH AND WE STILL DO NOT HAVE EMER LIGHTS WHEN PLACED IN ON POSITION. WHEN IN ARM, ALL LIGHTS ILLUMINATE EXCEPT THE OVERHEAD LIGHT IN LAV, THE FLOOR LIGHT IN LAV AND THE EXIT LIGHT ON BULKHEAD OUTSIDE LAV. CORRECTIVE ACTION: TROUBLESHOT AND FOUND #1, #2, #3 & #4 EMERGENCY BATTERIES WILL NOT HOLD A CHARGE.  REPLACED ALL 4 BATTERIES IAW CE680A AMM 33-50-06.  OPS CHECK GOOD.
