Well the ones I orderd said they were canbus but they don't work so I'm guessing there not or they have described item wrong in the add, me no not foot wells and puddles also I'm not needing number plate as I have already got let units in there ,
Are the sidelights you have canbus?
Is the interior fitted with a lights pack? that's they footwells and puddles?
what problems are you having with them?
I can provide a solution to sort the ones you have.
