## Discrepancy

THE PILOT REPORTED A VISIBLE PUFF OF SMOKE FROM THE OVERHEAD PANEL AREA TO MAINTENANCE.  MAINTENANCE FOUND TWO WHEAT BULBS BROKEN AND POSSIBLY SHORTED TOGETHER IN DE-ICE PANEL BACK LIGHTING.  NO OTHER ELECTRICAL ISSUES WERE FOUND.  ALL SYSTEMS WERE FUNCTIONAL.  THE BULBS WERE REPLACED AND OPERATED NORMALLY.
