that only happens with the cars that dont have HID xenons originally with no projector(the conversion kits dont have correct reflectors so the light energy dissapates wrong and causes the glare. The projectors generally solve this if they are high quality..
Range Rover and bmw provide the cars with a bulb with a slightly different temp. IMO the bmw's have much better light output even though the 4300 are the truest white. My bro's car has awesome light out put. The older zeds never had a true projector whereas the facelift does. Thats why pre-facelift lights arent great. You wont get glare when you upgrade the zed to a different temp lamp.
