CREW NOTED EMERGENCY LIGHTS IN OVERHEAD COCKPIT PANEL REMAIN ON WITH SWITCH IN OFF POSITION. MX FOUND WHEN THE L1 ENTRY LIGHT SWITCH IS TURNED OFF AT PANEL, EMERGENCY LIGHTS WILL EXTINGUISH.

MX FOUND FWD SERVICE ENTRY LIGHT ASSY MIS-WIRED.  WIRES WERE CORRECTED IAW WM 33-23-11 AND 33-51-12. OPS OF LIGHTS NOW CHECKS GOOD. MCO PLACARD REMOVED.
