Swift replacement lights

Johnc 26

I had a letter from Swift regarding a problem with locker lights causing discolouration presumably because of the heat. I have now received the new LED strip light replacements, and although they say it will only take 10 minutes per replacement, there are
6 of them and it includes removing some of the plywood innards. Has anyone had similar notification, if so how complex is it to complete. The diagram they send with the parts is not that great. Will be grateful for any advice. Or shouild I return the van to
the dealership, or Halfords as an authorised fixer.
