So I have a 2004 Toyota Celica GT-S with factory HID headlights. And have a couple of questions about new ones.

A. Spyder makes halo HID headlights. Will these work on my car? And has anyone ever heard of them having seal problems, because there is no back to them and it looks like they will get water damaged easily.

B. Should I just go buy factory HID headlights? My local dealer quoted me $750 plus shipping and handling. But Spyder I can pick up for less than $300.
