Old mining light (4,4)

I believe the answer is:

davy lamp

(Other definitions for davy lamp that I've seen before include "Mining illumination" , "Former source of mine illumination" , "Miner?s portable safety light" , "Coalminer's light" , "First generally-used safety light in coal mines" .)

I've seen this clue in The Sunday Times and The Times.
