Clothing and light got confused (7)
I believe the answer is:
garbled
'confused' is the definition.
(as in a garbled message)
'clothing and light' is the wordplay.
'clothing' becomes 'garb' (garb is a kind of clothing).
'and' says to put letters next to each other.
'light' becomes 'led' (light-emitting diode).
'garb'+'led'='GARBLED'
'got' is the link.
(Other definitions for garbled that I've seen before include "Distorted, confused" , "Mixed-up" , "(Message) corrupted" , "Confused, disjointed" , "Disjointed, incoherent" .)
