Bright side (6,6)
I believe the answer is:
silver lining
'bright side' is the definition.
(synonyms)
This is the entire clue.
(Other definitions for silver lining that I've seen before include "Redeeming aspect of an unfortunate situation" , "Redeeming aspect of unpleasant situation" , "offers hope in depression" , "Consoling aspect of a difficult situation" , "Compensating feature of cloud" .)
