Shiner on vessel from old part of Yorkshire land (6,5)
I believe the answer is:
riding light
'shiner on vessel' is the definition.
(light on a ship)
'old part of yorkshire land' is the wordplay.
'old part of yorkshire' becomes 'riding' (historical term for a region of Yorkshire).
'land' becomes 'light' (lighting is a kind of landing).
'riding'+'light'='RIDING LIGHT'
'from' is the link.
(Other definitions for riding light that I've seen before include "What ship at anchor shows" , "Illumination for ship at anchor" .)
