Palms off lights (5)
I believe the answer is:
lamps
'lights' is the definition.
(lamp is a kind of light)
'palms off' is the wordplay.
'off' indicates an anagram.
'palms' is an anagram of 'LAMPS'.
(Other definitions for lamps that I've seen before include "Devices for giving light" , "light fittings" , "Lights" .)
