I don't know the length cut-off where you have to have two separate white lights.
The major thrust of the white lights is that all power-driven vessels must show a white light continuously all around the vessel whether done by one or two lights. In my opinion one should not show two white lights (unless they are mast and range lights as on big vessels) at the same time, such as anchor and stern light. I have often wished I had a Letter of Marquis to write (and keep half for myself) citations for bad lights. They are almost always improper steaming light and occasionally the stern light. Sailboats often forget to turn on the steaming light when firing up the iron jib, many small runabouts have lights (when they remember to turn them on) occulted by biminis or people. On several occasions I have watched all the boats in the harbor from sundown to around 11pm and found 30 to 50 percent have illegal lights. The least compliant are trailer-sized runabouts, the most are commercial vessels. I have even seen red and green lights reversed on two occasions.
