thanks for all your help and replies. I must admit I have never had any bother with MOT where the lights are concerned on any machine I've owned as long as they light the road (even somewhat) and the aim is good. They must be a lot more vigilant in Wales than here? that ain't a bad thing unless the tester is just a pedantic old fool, at least a strict test can install confidence in the road worthiness of your bike. I have decided to go against the grain and fit a single 7" fitted with 100/90 H4 lamp with Cree spots either side. I will obviously post a pic or two when done to get some feedback.
