## Discrepancy

R1 EMERGENCY EXIT SIGN, R1 SLIDE LIGHT AND  EMERGENCY EXIT LOCATOR SIGN INOP DURING EMERGENCY  LIGHT TEST.    FOUND THAT AFTER AIRCRAFT HAD BEEN POWERED FOR OVER  AN HOUR, ALL LIGHTS WOULD TEST, HOWEVER THE TEST  ONLY LASTED APPROX 5-10 SECONDS, ALL OTHERS STAYED  ON FOR APPROX. 1 MINUTE.  AFTER TESTING, LIGHTS  WOULD NOT TEST AGAIN.  REMOVED AND REPLACED BATTERY  M730 IAW AMM 33-51-07-2, OPS CHECK GOOD,  LIGHT TEST NORMAL.
