Human Factors
[I was] PIC flying pilot. Requested vectors for the RNAV 28 approach in VMC conditions. Wind variable 3 kts. Turned on outside the final approach fix. Aircraft was configured and stabilized at FAF and checklist completed. Descended via VNAV to 100 ft. above MDA then transitioned to VASI at this time. Transition from VNAV to VASI was briefed prior and confirmed at transition. Autopilot and yaw damp were disconnected between FAF and transition. Crossing the threshold; we discovered that the landing lights were not on. As we touched down normally I called for landing lights and momentarily looked up and to right to confirm switch position. At this time; the aircraft drifted left and a slight impact was felt by both crew. Aircraft was returned to the runway centerline. Post flight revealed damage to the left trailing flap and left leading edge due to impact with runway edge lights. I believe the primary reason for the lateral deviation was me as flying pilot removing complete attention to the lateral path of the aircraft at such a critical moment of the flight. Although I only diverted my eyes for a second it was enough time to become disoriented enough to allow the aircraft to drift left during a dark night landing. Had I simply concentrated on the left and right runway edge lights in front of me the roll out would have been dark but normal. It is possible-but not common-for the landing lights to extend but not sequence on. This is a situation neither the SIC or me had seen before. I believe modifying the SOP call to 'landing lights extend/on' instead of the checklist response of 'as required' could help alleviate confusion for future crews.
