## Discrepancy

CENTER CABIN LIGHT GAVE OFF A WISP OF SMOKE IN FLIGHT. PILOT CONTINUED WITH FLIGHT AND MEL ON GROUND AT BASE. I COULD NOT VERIFY PROBLEM AND CHECKED BY REMOVING ASSEMBLY. NO RESIDUAL SMELL EVER DETECTED. CHANGE ONE SUSPECT BULB SHOWING AGE. CLEANED ASSEMBLY AND TESTED 8 MINUTES ON GROUND. NO DEFECTS NOTED. SUSPECTED CONDENSATION OF SOME SORT COOKING OFF (MEDESOL) AS BULBS GET EXTREMELY HOT. CLEARED MEL 06 DEC 2022 AFTER SEVERAL ATTEMPTS TO DUPLICATE SMOKE.
