Went ahead in terrible danger (3)
I believe the answer is:
led
'went ahead' is the definition.
(led the way)
'in terrible danger' is the wordplay.
'in' indicates the answer is hidden within the clue.
'LED' is hidden within 'terrible danger'.
(Other definitions for led that I've seen before include "sort of light" , "Emitter of light" , "Light-emitting diode (abbr.)" , "induced to" , "Took by the hand and showed the way" .)
