Disembark using a torch (6)

I believe the answer is:

alight

'disembark' is the definition.
(I've seen this before)

'a torch' is the wordplay.
'torch' becomes 'light' (I've seen this before).
'a'+'light'='ALIGHT'

'using' is the link.

(Other definitions for alight that I've seen before include "Leave a vehicle - burning" , "Small restaurant" , "Touch down" , "Get down from, say bus" , "Disembark, land" .)

I've seen this clue in The Sun.
