Light, light touch provided with hesitation (5)
I believe the answer is:
taper
'light' is the definition.
(taper is a kind of light)
'light touch provided with hesitation' is the wordplay.
'light touch' becomes 'tap' (I've seen this before).
'provided with' says to put letters next to each other.
'hesitation' becomes 'er' (sound used when hesitating).
'tap'+'er'='TAPER'
(Other definitions for taper that I've seen before include "Convex shape that narrows toward a point" , "Thin wick" , "On VHS he recorded" , "Waxed spill" , "Gradually become thinner" .)
