Very light for example (5)

I believe the answer is:

flare

'very light for example' is the definition.
(very light is a kind of flare)

This is all the clue.

(Other definitions for flare that I've seen before include "Warning light" , "Sudden burst of flame" , "Distress signal; burst out angrily" , "Feral kind of sudden activity" , "signalling light" .)

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