Stick to decent h4 bulbs, you will just blind people as the ek9 headlights are not "projector" so will just scatter the beam.
Look at PIAA bulbs or if on a budget then OSRAM nightbreakers or likes.
I check my headlights to a professional to adjust them on factory spec and it was like the factory ones .I think people get the impression its ok to run these hid kits and often say " never had any problems" etc.
Thats because the person you blinded cant even see after being hit with the beam to react and let you know!

lot off my friends said to me that is very bright put not blind them.(if you have the low beam)
anyway this is my opinion.
