View showing first and last of lighthouses on headland (9)
I believe the answer is:
landscape
'view' is the definition.
(natural view)
'first and last of lighthouses on headland' is the wordplay.
'first and last of lighthouses' becomes 'L and S' (first and last letters of 'lighthouses').
'on' says to put letters next to each other.
'headland' becomes 'cape' (I've seen this in another clue).
'lands'+'cape'='LANDSCAPE'
'showing' is the link.
(Other definitions for landscape that I've seen before include "Painters may paint it" , "scene" , "variety of shot" , "Picture showing countryside" , "Countryside painting" .)
