I have a HID kit on my car already, however the stock headlamp housings do not focus the light very well at all. I would like to upgrade to a projector style headlamp, but I have heard many horror stories of bad quality products and water getting into the headlight, etc.

Does anyone have any experience with aftermarket projector headlamp assemblies, and if so, which brands should I look at and which brands should I stay away from?
