Huh...dude a HID bulb throws light everywhere...that is why a projector is needed; to focus it. Every car forum I've been on makes fun of people who put a HID in a regular reflective housing; just is blinding with light going all over. Even when manufactures did it, it really was just some cheap trick they used to focus in the light. Do any cars with HID's nowadays not come with projectors? I've seen LED's with projectors take over.

There are many cars with projector lenses that use halogen bulbs. But the bulbs used in the projector housings do not, I repeat, do not have a shield on them. This is because the way a projector housing works, the lens (and if applicable, the shield build into the housing) does all the focusing. In some projector setups, both high and low beam patterns are available and are controlled with a movable shield.
Few more that claim it is wrong (sure it can be done though):

P.S. HID's in a reflector case is actually illegal in some states and you can get a ticket for it
EDIT: Since you said your Maxima has a heated stearing wheel I'll assume it had the "Driver Preferred Package" which did have HID's, but I still tell you man that was just some cheap trick to focus the light Maxima did. You are by far not getting true HID lighting....this is one loophole where it is legal since from manufacturer, but again they must have made a special housing to focus that light.
