The video clip is good and I don't disagree on HIDs are not designed for a halogen housing. This can be easily explained that the latest/higher end HID equipped vehicles are using projector lens. However, some current and earlier models (i.e., Toyota Avalon, Nissan Altima, Last generation Lexus RX, GS, and LS, Last generation Acura TL, etc) are still using the halogen housing for HID. How do the factory vehicles get away with this? Answer: >>> A carefully adjusted light beam<<<
The HID kit illuminates better than conventional halogen and it needs to be re-aligned after the installation so the light is not offensive to the on-coming traffic.
The HID kit is not for everyone, it's just an alternate option to "oconn11" original post.
