LED's dead, eh? Change it (6)
I believe the answer is:
headed
'led's' is the definition.
('head' can be a synonym of 'lead')
'dead eh? change it' is the wordplay.
'dead eh' anagrams to 'HEADED'.
Though, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for headed that I've seen before include "Titled; topped" , "Led" .)
