I am in the motorway now going from Newcastle to London just bought the caravan. Unfortunately I had to drive without lights because when I connected the lights isn’t working. I think once arrive London will take it into a garafage. Any recommendation?

Thanks for the answer guys but I can’t figure out how make it work I have connected the fuses etc... but nothing. Also I want to ask if you thing that a BMW X3 3.0d m sport 2007 will be okay for a caravan of 83 inch wide
235 length
88 height ?

Thank you very much
