'use new match about lamp' is the definition.
I can't tell whether this definition defines the answer.

'about lamp' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'lamp' becomes 'light' (I've seen this before).
're'+'light'='RELIGHT'

Can you help me to learn more?

(Other definitions for relight that I've seen before include "The girl (anag)" , "fire again?" , "Ignite again" , "get going over" , "Rekindle" .)

I've seen this clue in the Sydney Morning Herald.
