I believe the answer is:

lit

I'm a little stuck... Click here to teach me more about this clue!

'came down' is the definition.
(light or alight can mean to land)

I cannot understand how the remainder of the clue works.

(Other definitions for lit that I've seen before include "books etc?" , "Set alight" , "was illuminating" , "Enlightened" , "Set fire to" .)

I've seen this clue in the Evening Standard.
