## Discrepancy

SEVERAL EMERGENCY LIGHTS NOT WORKING.  INTERIOR RIGHT SIDE OF AIRCRAFT ON FLOOR LIGHTING   BOTH EXTERIOR OVER WING EMERGENCY LIGHTS NOT WORKING.   DEBRIEFED THE CREW EARLIER, AND UPON POWER-UP, WE FOUND THAT ELPS 2 WAS NOT ILLUMINATING THE DESCRIBED EMERGENCY LIGHTS. WE ALLOWED THE ELPS #2 TO CHARGE, PERFORMED THE OPERATION TEST PROCEDURE FOR THE EMERGENCY LIGHTING POWER SUPPLIES I.R.W. GL-7500 AMP BD700-A-J33-51-00-02AAA-320E-A, AND THE TEST WAS FOUND SATISFACTORY. ADVISED NJA MCC, AND THEY STATED IT WAS OK TO RELEASE.
