Lift light beams that can be picked up (5)
I believe the answer is:
Here is my best explanation:
'lift' is the definition.
(raising is a kind of lifting)
'light beams that can be picked up' is the subsidiary indication.
'light beams' becomes 'rays' (I've seen this before).
'that can be picked up' shows a homophone (sound like).
'rays' is a homophone of 'raise'.
(Other definitions for raise that I've seen before include "collect", "Lift, elevate", ". . . put up", "wage increase", "Erect; grow", "uplift", "better?", "Amplify", "Hoist" and "contact".)
