## Discrepancy

EMERGENCY LIGHTS IN SUPERNUMERARY ILLUMINATED ON  SHORT FINAL TO LANDING. STAYED ON FOR ABOUT 10  SECONDS. COMPLIED WITH OPERATIONAL CHECKS AND FUNCTIONAL  CHECKS PER AMM 33-51-00-5. ALL TESTS PASSED AND  OBSERVED THE A/C FOR 20 MINUTES WITH NO DEFFECTS  NOTED. SUSPECT THE NEW BATTERIES THAT WERE  INSTALLED JUST NEEDED SOME TIME TO COMPLETLY  CHARGE. A/C IS OK FOR SERVICE.
