## Discrepancy

UPON LANDING, THE AFT OVERHEAD LIGHT PANEL STARTED TO FLICKER ON AND OFF THEN THE ODOR AND SMOKE WAS IN CABIN.  DISASSEMBLED THE OVERHEAD LIGHT PANEL AND NOTED THAT THE SOCKET FOR THE BULB HAD CRACKED. THERE WAS EVIDENCE OF OVERHEATING IN THE SOCKET DUE TO THE POSITIVE AND NEGATIVE TERMINALS TOUCHING, WHICH STARTED TO MELT THE PLASTIC IN THE SOCKET ASSEMBLY. THE POWER WIRES TO THE LIGHT ASSEMBLY WERE CAPPED AND STOWED AS NECESSARY. THE AFT CABIN LIGHT ASSEMBLY WAS PUT UNDER AN MEL AND THE ACFT WAS RTS.
