Good car is lit unconventionally for a specialist (12)

I believe the answer is:

cardiologist

'a specialist' is the definition.
(cardiologist is a kind of specialist)

'good car is lit unconventionally' is the wordplay.
'unconventionally' indicates anagramming the letters.
'good'+'car'+'is'+'lit'='goodcarislit'
'goodcarislit' with letters rearranged gives 'CARDIOLOGIST'.

'for' acts as a link.

(Another definition for cardiologist that I've seen is " Specialist in heart disease".)

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