I presume H7R is for reflector lamps?
The freeform reflector lamps have always produced terrible results with retrofitted HIDs, as opposed to ellipsoidal projector headlamps which are usually as good as OE.
Did you bulbs have a black or silver band around them? If so, this might help by shortening the arc to H7 standard.
MOT testers are supposed to check the source of light matches that of the lamp, but in practice, this is all but impossible, and their manual says to err on the side of assuming it's OK. Don't worry about E marks and they are not required for the MOT and the HID kits are usually made form standard E-marked electronic parts in any case.
