Wooden container with lever touching top of light (6)
I believe the answer is:
barrel
'wooden container' is the definition.
'lever touching top of light' is the wordplay.
'lever' becomes 'bar' (a lever is a bar attached to a machine).
'touching' becomes 're' (I've seen this in other clues).
'top of' suggests taking the first letters.
The first letter of 'light' is 'l'.
'bar'+'re'+'l'='BARREL'
'with' acts as a link.
(Other definitions for barrel that I've seen before include "Cylinder with metal hoops" , "Round wooden vessel." , "full of laughs?" , "Cask, drum" , "Tun" .)
