Novsight led does not will not fit peugeot 807 projector H7 lense.

seams that the great NOVSIGHT h7 led has failed on my car.
i am not 100% sure at which point it is rubbing and what makes it not lock in the adapter. so i just put them to high beam and it's really amazing amount and quality of light for high beam (just how ofter will you use it. )
UPDATE. I didn't give up and tryed other h7 LED for my low beam and it worked and came in perfect.
and NOVSIGHT NON FITTING could also do with the size of a fan or smth.
