I believe the answer is:

nettled

I'm a little stuck... Click here to teach me more about this clue!

'cross seen in clear light?' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?

'cross seen in clear light?' is the wordplay.
'cross' becomes 'T' (shape).
'seen in' is an insertion indicator.
'clear' becomes 'net' (as in net profit).
'light?' becomes 'LED' (light-emitting diode).
'net'+'led'='netled'
't' placed inside 'netled' is 'NETTLED'.

Can you help me to learn more?
