Spirit used in petrol lighters (5)

I believe the answer is:

troll

'spirit' is the definition.

'in petrol lighters' is the wordplay.
'in' indicates a hidden word.
'TROLL' can be found hidden inside 'petrol lighters'.

'used' acts as a link.

(Other definitions for troll that I've seen before include "Fairytale monster" , "Mythological being" , "unwanted contributor to site?" , "Online annoyance" , "Supernatural creature of Scandinavian folklore" .)

I've seen this clue in The Globe and Mail.
