Hi,Hej och valkommen....... I have looked at my UK handbook,read, and re-read the fuse locations......and I can't find the number plate fuse!! There is three fuse box locations,so I would look at the boot fuse box first.....If you have a 12 volt tester,then check each one.This is usually quicker and more reliable than removing each fuse and looking at the "broken" link. I would be inclined to look at the bulbs first,it could be a slightly corroded brass lamp holder....a little Emery paper to clean up might be the answer? Lycka Till..... Ian
