The navigator can move forward by the centre of a narrow channel when the two lights are aligned, separating them when the vessel strays from one side; this provides information on his position outside the leading line. When these lights are synchronized, they are much more conspicuous to distinguish them in locations with strong background lighting.
The MRL light produces an unidirectional beam with a horizontal divergence from 2.0° to 4.3°. Its luminous source, consisting of high-power LEDs of 100,000 hours average life, makes it a maintenance-free beacon.
