## Discrepancy

DURING LINE CHECK, FOUND FLOOR PATH EMERGENCY LIGHTS INOPERATIVE ON THE LEFT SIDE OF THE AIRCRAFT AND BETWEEN DOOR 2R AND 3R.  REPLACED THE POWER SUPPLY FOR THE LIGHTS ON THE LEFT SIDE OF THE AIRCRAFT AND REPLACED A LIGHT ASSEMBLY TO REPAIR THE LIGHTS BETWEEN DOOR 2R AND 3R.  OPERATIONAL CHECK GOOD.
