Light interior design it elucidated (6)

I believe the answer is:

ignite

'light' is the definition.
(I know that light can be written as ignite)

'interior design it elucidated' is the wordplay.
'interior' says the answer is hidden in the clue (I've seen 'interior of' mean this).
'IGNITE' is hidden in the letters of 'design it elucidated'.

(Other definitions for ignite that I've seen before include "Kindle Fire" , "Detonate" , "Combust" , "Touch off; inflame" , "Cause to catch fire" .)

I've seen this clue in the Sydney Morning Herald.
