## Discrepancy

APPARENT LIGHTNING STRIKE CAUSED ENGINE FIRE WARNING TO ACTIVATE.  THE WARNING WOULD NOT RESET.  SUBSEQUENT ENGINE SHUTDOWN HAD NO AFFECT ON WARNING.  BOTH ENGINE FIRE EXTINGUISHERS WERE DISCHARGED.  FIRE WARNING STILL INDICATED.  DECLARED EMERGENCY, LANDED UNEVENTFULLY.   INSPECTED ENGINE AND THERE WAS NO IDICATION OF FIRE.  DISCOVERED LIGHTNING STRIKE SIGNS.
