I considering getting a set of hid's for my 99.5 a4. But before I start doing any shopping I had a few questions. I have the one piece lens with h4 projectors right now. Am I going to be okay just buying one of these "conversion kits" that will allow an hid blub to fit in my lens. I mean is the hid going to look right coming from my projector or is there a difference in projectors in the hid specific lenses (such as the ones that come on the s4), besides the auto leveling feature?

 

And also any suggestions on a good place to buy hid parts at?
