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

'light on pool by day' is the wordplay.
'light' becomes 'glim' (I've seen this in another clue).
'on' is a charade indicator (letters next to each other).
'pool' becomes 'mere' (mere can mean a lake).
'by' says to put letters next to each other.
'day' becomes 'd' (abbreviation for day).
'glim'+'mere'+'d'='GLIMMERED'
