Prop for Diogenes (7)

I believe the answer is:

lantern

(Other definitions for lantern that I've seen before include "Transparent case for candle" , "Cased lamp" , "Light in a protective casing" , "Light-admitting structure on roof" , "It illuminates" .)

I've seen this clue in The Wall Street Journal.
