## Discrepancy

DURING MAINTENANCE BASE INSPECTION FOUND THAT THE FORWARD EMERGENCY LIGHTS WILL NOT ILLUMINATE.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  REMOVED AND REPLACED THE NR 1 POWER SUPPLY, BATTERY IAW 33-700-19 AND INVERTER IAW EMBRAER 145 AMM 33-50-11.  OPERATIONAL CHECK WAS GOOD.  THE AIRCRAFT WAS RETURNED TO SERVICE.
