## Discrepancy

(CAN) WHILE PERFORMING DAILY INSPECTION AND REPORTED INTERMITTENTLY BY PILOT THAT TWO LIGHT SWITCHES ON CONTROL PANEL.  OCCASIONALLY WILL NOT SWITCH (OFF) OR SOMETIMES WILL NOT REMAIN IN (ON) POSITION THIS WOULD OCCUR INTERMITTENTLY AND IT WAS DISCOVERED. PROBLEM IS AN INTERNAL MALFUNCTION. THIS OCCURRED ON (STROBE/BEACON) SWITCH AND (TAXI/LOGO) LIGHT SWITCH.  BOTH SWITCHES ARE THE SAME PN.  SWITCHES REPLACED WITH NEW.
