I got pulled in my vw passat just before my birthday last year, someone had put the wrong bulb in the rear so my third brakelight was always illuminated.

I thought i'd got two months mot still turns out it was around 2 months out of date. I had my picture taken by the police officer, got a £60 fine and that was it. Left to carry on my journey for the rest of the night. I paid the fine and that was it.
