Late on 23 September, the navigational lights for a ship were sighted.

With their regular navigational lights off, the F-14 was virtually invisible.

Each of these structures had a navigational light placed upon it, locally maintained at first, and then after 1873 by the lighthouse service.

Three minutes after the radar came on, lookouts spotted a ship's navigational lights.

The first navigational light on Sand Key was a 60-foot brick tower built in 1827.

The entire trip was flown without even navigational lights.

It was coming almost directly towards them, both the green and red navigational lights showed.

The fishing boat had been underway without navigational lights and only showed up on the ship's radar at the last moment.

This is the earliest record of a navigational light in Cornwall.

There is a navigational light set up on the highest point on the island.
