Last night my headlights main beam stopped working both of them, checked fuses under steering wheel all fine. At the same time a brake went and rear lights. I’ve fixed these. Does anyone think it’s a bad earth causing these all to go at same time.

Hi I’m new here and was hoping for advice, is the issue resolved with the diff on the freelander 2 and also where to buy mud and snow tyres 235 50r 18
