was going to pm you but thought it better to tell everyone that wants to know what the definitive daytime MOT is, according to my interpretation.
There is no 'Daytime MOT' as such. But...........
If a motorcycle is presented for MOT test with ALL lamps removed, painted over or masked, the lighting inspection does not apply and the owner will be issued with an advisory notice stating that vehicle is only to be used during daylight hours / not used at times of reduced visibility. This wording doesn't even appear on the MOT certificate, just on the VT32 (advisory notice) which you are entitled to throw away!
Therefore a trackday bike will only require a single tone horn, regulation size numberplate and all the normal trackday cycle parts in proper order. (tyres etc etc)
Even a race can with 'not for road use' will pass if the wording is covered over, as long as the sound is not excessive (testers discretion).
Speedo is not part of the MOT either so you can't fail on that account.
For those that disagree, bear in mind that I passed my MOT testers course 4 months ago and it was the exact questions you've posted on here that I asked the VOSA examiner on my course as I wanted a difinitive answer as I usually run a trackbike on the road without lights.
For those of you darn sarf who want to get your trackbikes through an MOT, give us a shout.
