Doctor had ample light (8)
I believe the answer is:
headlamp
'light' is the definition.
(I know that headlamp is a type of light)
'doctor had ample' is the wordplay.
'doctor' indicates anagramming the letters.
'had'+'ample'='hadample'
'hadample' anagrammed gives 'HEADLAMP'.
(Another definition for headlamp that I've seen is " Chief light on car".)
I've seen this clue in The Times.
Want a hint initially instead of a full solution?
