One has given out a little light, being won over (9)

'won over' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps there's a link between them I don't understand?

'one has given out a little light' is the wordplay.
'one' becomes 'ied' (I can't justify this - if you can you should give a lot more credence to this answer).
'has' indicates putting letters inside.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'a little' indicates taking the first letters.
The first letter of 'light' is 'l'.
'given' is an anagram of 'nveig'.
'nveig'+'l'='nveigl'
'ied' placed around 'nveigl' is 'INVEIGLED'.

'being' acts as a link.
