The standard headlights were never designed to be fitted with HID Globes. I think it is also illegal to have them fitted for the same reason. They give off too much glare to other drivers. The headlight reflectors and lenses of OEM HID headlights (=optics) are engineered specifically for use with HID arc capsules. The design not only considers the source focal points, but the amount of lumen to be distributed. These factors are often overlooked when retrofitting is considered. OEM HID optics distributes the increased lumen output of this bulb farther ahead on the road, wider to both sides, without giving more directly in front of the subjected vehicle. This provides motorists with much WIDER AND DEEPER night time vision. By contrast, halogen headlight optics do not spread the light to the degree of OEM HID. This is simply because a 55 watt halogen bulb (or even a 100 watter) cannot match the lumen output of HID. A lower number of lumens means less light to spread out. And a bigger portion of the total light output have to be placed where its mostly needed: straight ahead. Now, consider what what happens when someone inserts a 2800-3200 lumen HID arc capsule into a headlight designed to distribute only 1/3 of this amount of light. Suddenly, there's too much light in areas that does not need more light: Too much light above cutoff line which would be above horizon on a flat road. This will glare oncoming traffic. Too much light below cutoff line which would glare dangerously towards oncoming traffic on a hill. Too much foreground lighting. The driver will get the intense foreground lighting back in his own eyes, making eyes less sensitive for down the road illumination beyond 70 meters down the road. More info here !
