Ray of solar light (7)
I believe the answer is:
sunbeam
'ray of solar light' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sunbeam that I've seen before include "Bright shaft of daylight" , "Ray of solar light" , "Ray of natural light" , "Bright ray -- bus name (anag)" , "sheds a bit of light" .)
