In your opinion, continuation of a safe approach to the landing threshold is questionable.
The aircraft passes over landing threshold.
The pilot reports the runway/approach lights in sight and requests to or advises that he/she will proceed visually.
NOTE: A pilot’s report of “runway in sight” or “visual” is not a request to proceed visually.
When precision approach guidance is discontinued in accordance with subpara a, advise the aircraft of its position and to proceed visually.
(Distance) MILE(S) FROM TOUCHDOWN, PROCEED VISUALLY (additional instructions/clearance as required).
After a pilot has reported the runway/approach lights in sight and requested to or advised that he/she will proceed visually, and has been instructed to proceed visually, all PAR approach procedures must be discontinued.
Continue to monitor final approach and frequency. Pilots must remain on final controller’s frequency until touchdown or otherwise instructed.
