What was found
WHILE DESCENDING INTO NAPLES, THE MASTER WARNING SWITCH LIGHT AND BAGGAGE SMOKE ANNUNCIATORS ILLUMINATED. WE DECLARED AN EMERGENCY AND REQUESTED VECTORS TO THE CLOSEST AIRPORT WITH ARFF ON THE FIELD, WHICH WAS TMB. THE ONLY ITEM ON THE CHECKLIST WAS LAND AS SOON AS POSSIBLE. WE CONDUCTED A DESCENT AND MADE AN UNEVENTFUL LANDING AT TMB. UPON LANDING, WE EVACUATED THE AIRCRAFT ON A TAXIWAY AND HAD IT INSPECTED BY ARFF. NO EVIDENCE OF FIRE OR SMOKE IN THE FORWARD OR AFT BAGGAGE COMPARTMENT WAS PRESENT.
