Fog Light

[cubaton3]

Hello, I don't know much about the fog lights world, I'm been planning on adding fog lights to my coupe, many of you guys have them. I would like to know which fog lights I should purchase? I don't want a switch, I would like for them to turn on automatically when I turn on my headlights, I have white hid's so I'm looking for fog lights that are white, I don't want yellow, purple looking fog lights, anybody send me a link of which I could buy? Thanks, and remember my car is 2009 but has a 2012 front fascia.
Thanks for any of you that will help me out on this. Thanks
