Alight on the bench (6)
I believe the answer is:
settle
I believe this is a double definition.
'alight' is the first definition.
(I've seen this before)
'the bench' is the second definition.
(settle is a kind of bench)
'on' acts as a link.
(Other definitions for settle that I've seen before include "Solve" , "Pay up or sink down" , "rest > put in order" , "perch" , "Make home, put down roots" .)
