Camper's light (7)
I believe the answer is:
lantern
'camper's light' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lantern that I've seen before include "Light in a protective casing" , "Top of lighthouse" , "Type of lamp" , "Lamp with protective transparent casing" , "Light in a transparent protective case" .)
