He actually asked if it was legal not would it pass an MOT inspection. You would not get pulled by the police for having a non working high level brake light.Obertelli said:I hate to disagree but as far as I recall any cars manufactured after whatever date they were compulsory from should not pass an MOT if the 3rd light isn't working. However there's a peculiarity in the law whereby if the light has been removed or deliberately disconnected (i.e. wiring connecton physically removed) then they're not an MOT item at all.
Perhaps a well trained MOT tester can confirm this, but I'm sure that I'm correct (I think I read it on this forum yonks ago, but the thread has been archived/deleted).
