Article 110 Dangerous lights
A person shall not exhibit in the United Kingdom any light which:
by reason of its glare is liable to endanger aircraft taking off from or landing at an aerodrome; or
by reason of its liability to be mistaken for an aeronautical ground light is liable to endanger aircraft.
If any light which appears to the CAA to be such a light as aforesaid is exhibited the CAA may cause a notice to be served upon the person who is the occupier of the place where the light is exhibited or has charge of the light, directing that person, within a reasonable time to be specified in the notice, to take such steps as may be specified in the notice for extinguishing or screening the light and for preventing for the future the exhibition of any other light which may similarly endanger aircraft.
The notice may be served either personally or by post, or by affixing it in some conspicuous place near to the light to which it relates.
In the case of a light which is or may be visible from any waters within the area of a general lighthouse authority, the power of the CAA under this article shall not be exercised except with the consent of that authority.
