Nice 1 thanks for all your advice, that’s put my mind at ease! Did it affect the beam pattern after you removed it, I don’t even know what it’s for!
The lights are pretty ropey at the best of times, as long as beam is at the correct height and direction it'll be fine in an MOT.
In fact is it's not the bulbs that are the issue, it's the reflective part of the housing that is the problem, it's simply not very good. Putting the best bulbs in like Osrams for example can help a little, but not much to be honest. A lot of people add LED spotlights which help massively, plus i also use mine as daylight running lights as well, as they use very little power in comparison to the headlights and are very bright.
