For some reason my lights are off during the night and on during the day, I cannot see how fast I’m going at night. This randomly reversed one day when turning on the car, and to make it worse, almost all of my interior lights are no longer functioning now (which was not the case before).

 

Ist rule of auto electrics .....Pick on one light that should be on but isnt and fault find that one ....earth ...live etc the result will probably put them all right
