Big fires for pleasure in the open (8)

I believe the answer is:

bonfires

(Other definitions for bonfires that I've seen before include "They're lit at Halloween" , "Outdoor burnings at 19 dn" , "No briefs (anag.)" , "They're lit as signals or in celebration" , "These strange conflagrations are a Norse fib" .)

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