Barge; smoker's accessory (7)
I believe the answer is:
lighter
This clue is a double definition.
'barge' is the first definition.
(I know that lighter is a type of barge)
'smoker's accessory' is the second definition.
(a cigarette lighter)
(Other definitions for lighter that I've seen before include "Boat for heavy loads and fire igniter" , "that leads the way for others?" , "Kind of barge - carrying less?" , "more blonde" , "Cargo barge; smoker's accessory" .)
