Fit Fuses

The small light fuse on my 07 Fit keeps blowing. It runs some dashboard back lights and the rear running lights. It never happens while I’m driving, but when I start the car the lights don’t turn on. At first I thought I’d just keep plenty of extra fuses and replace as needed, but last time it only lasted about 8 hours. Any thoughts?

Even myself being an experienced and certified auto electrican would need a look at the schematic on this, just so I could be certain on just what is protected by this fuse. I am not trying to make the job bigger than it needs to be just relating proper repair procedure.
