Type of light lake punt Royal Navy pursues (7)

Ross

I believe the answer is:

lantern

'type of light' is the definition.

'lake punt royal navy pursues' is the wordplay.
'lake' becomes 'l' (geographical abbreviation).
'punt' becomes 'ante' (anteing is a kind of punting).
'royal navy' becomes 'RN' (abbreviation for Royal Navy).
'pursues' is a charade indicator (letters next to each other).
'l'+'ante'+'rn'='LANTERN'

(Other definitions for lantern that I've seen before include "Transparent case for holding a light" , "Light in a protective casing" , "It illuminates" , "Enclosed light" , "Light in a transparent protective case" .)

I've seen this clue in The Telegraph.
