Hal Jordan was eventually revived and once again became a Green Lantern . He also made an oath to recharge the power ring : `` In brightest day , in blackest night No evil shall escape my sight , Let those who worship evil 's might , Beware my power ... Green lantern 's light ! '' Since Green Lantern : Rebirth and the restart of the Green Lantern Corps , the only oath used has been the Brightest Day , Blackest Night version .
