Narrative:

Crew landed without specific knowledge of landing clearance. Upon rollout on runway 27L the captain and first officer noticed at the same time approach clrncs coming over the radio. Day VMC conditions prevailed, and we were cleared a visual approach on a left base. The PF was working to reduce speed and altitude while trying to lower flaps within limit speed. The PNF was focused on completion of the landing checklist which was not completed until after the final fix. The aircraft was in a stable approach condition by 500 ft AGL. The runway was cleared visually of any traffic. The captain noticed after rollout that he had not turned on the taxi light during landing. This is his indication of landing clearance. The first officer does not have a specific technique to identify whether a landing clearance has been received.
