## Discrepancy

IN-FLIGHT, PILOT SELECTED PANEL LIGHTS ON, SMOKE BLEW OUT OF THE INSTRUMENT PANEL INSTANTLY.  PILOT SHUT OFF ALL POWER.  SAFE LANDING WAS MADE.  FOUND PANEL LIGHT DIMMER ASSY BURNT AND SHOWS SIGNS OF HIGH HEAT.  INSPECTED ALL ASSOCIATED WIRING, NO DEFECTS NOTED.  INSTALLED NEW DIMMER ASSY.  OPS NORMAL.  PILOT REPORTS THIS IS THE SECOND TIME IN 4 YEARS THAT THIS SAME PROBLEM OCCURRED.  POSSIBLE DEFECTIVE DIMMER UNIT.
