all aftermarket housing have crappy output, hotspots, irregular pattern, FOUL cutoff, they don't concentrate on the optics very well, that's why they are MUCH cheaper than OEM. The only housings that responds to hid very well are OEM. If they are true JDM knock-off with the flare to the wrong side they would be obnoxious with HID, you would be blinding every single passing car, and I don't mean a mild streak of light past their eyes, I mean they would get to see the beam first hand as bright as can be. For the price of those housings and that HID kit you could get a bi-xenon BMW complete setup. For few hundred see_fu would install them in your housings for you, and you will have better light than you ever thought possible. I detest real HID kits in bad housings, it hurts other drivers.
