They changed the laws in the UK, in 2020 you couldn't fit led bulb conversions.
I suppose due to the prolific amount of led usage and drls they changed their minds.
Now as long as the angle is ok they are not allowed to fail them.
I read that these bulb conversions don't fit the GRiSO nacelle.
Bought me one of these and a couple of those push fit side light leds on lcjohnny's recommendation. He posted it somewhere.[You must be registered and logged in to see this image.][You must be registered and logged in to see this image.]
They may not fit your GRiSO headlight nacelle but they certainly fit mine.
Removed the 3 right angled females from the H4 connection, then fitted them direct to the led headlight bulb replacement.
A quick 45 degree bend and the non fittment issue was corrected.
Fits perfect and can adjust headlight angle.
Took me 10 mins, piece of pish and only cost £25 all in
Non of this swap this, swap that, adjust this, drill this, drill that, spend £100's of quids (almost a grand for some) for some fancy DRL (all made in china) with a shitty plastic lens scratches first time you clean off the bugs.
Oh yea and condensates, least it matches ya dash! [You must be registered and logged in to see this image.]
