Hello all this is my first time here. I have a 2000 plate Fabia. I recently had my light out warning light come on but with no bulbs out. Then shorty after the brakes lights came on but only half brightness now stay on. Then the indicators stayed in the drivers side all three of them again constant but only half brightness. Now to top it off my rear fog lights come on every time I turn my normal lights on currently checked all the earths replaced the brake light switch and nothing seems to Be working 

checked earths--- did you strip and clean?
