One may take such a view of poor lighting (3)
I believe the answer is:
dim
'one may take' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Perhaps you can see an association between them that I don't see?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for dim that I've seen before include "Without much light" , "out of mind?" , "Not shining brightly" , "thick" , "Darken" .)
