## Discrepancy

AIRCRAFT  WAS ON A REPOSITIONING FLIGHT.  PILOT NOTICED SMOKE COMING FROM OVERHEAD PANEL.  AT ABOUT 9:45PM HE DECLARED AN EMERGENCY AND DIVERTED.  LANDING SAFELY. THE ACFT HAS BEEN RETURNED TO SERVICE.  INSPECTED OVERHEAD ELECTRICAL PANEL AND FOUND CAUSE OF SMOKE TO BE 2 EA LIGHT BULBS ARCING OUT ON RIVET IN UPPER LT CORNER.  FURTHER INSPECTION OF REMOVED PANEL SHOWED CAUSE TO BE CORROSION BRIDGING ACROSS COPPER TRACKS, CREATING 2 SHORT CIRCUITS.
