## Discrepancy

LOWER EMERGENCY EXIT SIGN LIGHT DOES NOT ILLUMINATE  TECHS GOT ONISTE AND VERIFIED THAT THE AFT EMER LIGHT WAS INOP. TECHS THEN SWAPPED THE AFT EMER LIGHT TO THE FWD AND FAULT DID NOT FOLLOW. WE THEN PUT EVERYTHING INTO NORMAL CONFIGURATION AND ALL LIGHTS ARE OPERATING NORMALLY. NO DEFECTS NOTED AT THIS TIME. ALL WORK PERFORMED IAW AMM 33-52-15.
