Help WIth After market HIDs and fog lights

Hello all. I just bought my first Prius. Its an 08 package #2 in superwhite. I really wanted the HID and fog lights but not with all the other stuff i had to buy to get them. I have a few questions I hope some of you out there can help me with. Where can i get a good aftermarket HID kit? About how much are they going for? I am not real car handy so I would probably have to go to a shop and really don't want to get ripped off. Same thing for fog lights. BUT THE BIGGEST QUESTION IS.........would installing aftermarket lights VOID my warranty. I got the extended warranty, and I would hate to be paying for nothing.


Thanks In Advance
A very Happy Prius Owner
