Dreaded MOT on saturday, and i appear to have an issue with my afterburner lights. I've noticed that there are 3 leds off on both sides. as these are LED lights, what are the legalities of passing/failing the mot due to this? is there a set number that have to be on dependant on how many there are, or is it an instant fail? its not as though you cant see them as they are really bright, but i'm concerned that it is gonna fail due to that

cheers
