Wander in street with just a bit of light (5)
I believe the answer is:
stray
'wander' is the definition.
('stray' can be a synonym of 'wander')
'street with just a bit of light' is the wordplay.
'street' becomes 'st'.
'with' says to put letters next to each other.
'just a bit of light' becomes 'ray'.
'st'+'ray'='STRAY'
'in' is the link.
(Other definitions for stray that I've seen before include "Appearing occasionally" , "Depart from the right path" , "digress" , "Lost pet" , "Waif and - -" .)
