Glow in arcade lit (8)
I believe the answer is:
radiance
'glow' is the definition.
(I've seen this before)
'in arcade lit' is the wordplay.
'lit' indicates anagramming the letters (lit can mean drunk).
'in'+'arcade'='inarcade'
'inarcade' is an anagram of 'RADIANCE'.
(Other definitions for radiance that I've seen before include "Luminosity; splendour" , "Glowing quality" , "Great joy" , "Brightness" , "moonlight" .)
