I currently have the Vision K2 HID kit in my Accord. The glare is very very bad, and I want to switch to projectors. I plan on:

1. Buying aftermarket projector headlights.
2. Buying a set of OEM HID projector lenses ( Audi,BMW,LandRover,Honda, ect.)
3. Then I want to swap out the aftermarket projector lenses with the OEM HID projector lenses.

So my question is if there is anything that I should look out for or that I'm leaving out??? My only worry if I ever get the RangeRover
projectors, is that it might be too big to fit. Also would I be able to use my current HID lights with the OEM projectors, or would I be better of using OEM HID's as well?
