11 years imprisonment iirc
+1 this is what i was told!Any car is not required to have a 3rd brakelight wether it was manufactured with one or not. Mot wise if there is one their/ a red lens the light must work but you can either remove bulb and spray lens black and it will pass, so if your new spoiler doesn't have one fitted at all then that's fine just make sure your 2 rear brake lights are always working.
