Carefree, putting the dear new lamp in front (5,7)

I believe the answer is:

light hearted

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

'the dear new lamp in front' is the wordplay.
'new' indicates anagramming the letters.
'lamp' becomes 'light' (I've seen this before).
'in front' means one lot of letters go next to another.
'the'+'dear'='thedear'
'thedear' anagrammed gives 'hearted'.
'hearted' after 'light' is 'LIGHT-HEARTED'.

'putting' acts as a link.

(Another definition for light hearted that I've seen is " carefree".)

I've seen this clue in The Daily Express.
