Brilliant, shining (8)
I believe the answer is:
dazzling
This clue is a double definition.
'brilliant' is the first definition.
(I've seen this in another clue)
'shining' is the second definition.
(thesaurus)
(Other definitions for dazzling that I've seen before include "Brilliant" , "Amazingly impressive (like car headlights?)" , "Very bright, impressive" , "Shining intensely" , "Blinding" .)
