No lights at all (so if you have a brake-light, you must have all lights).
No speedo required (for any MOT)
Horn is required (even if a battery operated bicycle thingy)
Number plate with a little stick on reflector and tyres that aren't marked up "not for road use".
Rest of vehicle must be roadworthy.
Its not actually a daylight MOT as such. Its a full certificate with an advisory to state "no lights were fitted at the time of testing".
Thanks mark for that explanation, if i had a pound for every time i had to explain there is NO such thing as an Daytime MOT !!!! well you know the rest.
