BRITISH EMPIRE.

SIGNALS TO BE MADE BY VESSELS APPROACHING PORTS WHEN INCONVENIENCED BY SEARCHLIGHTS.-Any vessel approaching a port in the British Empire when searchlights are being worked, and fearing that they will interfere with her safe navigation, may make use of the following signals, either singly or combined :—
(a.) By flashing lamp, four short flashes followed by one long flash.
(b.) By whistle, siren, or fog-horn, four short blasts followed by one long blast.
Whenever possible, both flashing lamp signals and sound signals should be used.
On these signals being made the searchlights will be worked as far as circumstances will permit, so as to cause the least inconvenience, being either extinguished, raised, or altered in direction.
The signals should not be used without real necessity, as unless the vessel is actually in the rays of a searchlight it is difficult to know which searchlight is affected. The signals should be repeated until the inconvenience is removed.
NOTE.-These signals are designed to assist mariners and do not render the Government liable in any way.
