Flare that's easily transported (4,5)
I believe the answer is:
very light
'flare' is the definition.
(I know that Very light is a type of flare)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for very light that I've seen before include "Warning signal" , "Signaller's item" , "sort of flash" , "Gun-fired flare" , "Pistol flare" .)
