Could I buy these lights and then take the xenon lights from my current stock headlights and put them in there?

 

Oh god lord. Why would you want to put these ricer lights on your nice car?

 

I vote no to this idea as well.

 

+1 as well, Angel eyes looks good on BMW's, personally I wouldn't think about installing those, I'd keep my stock Xenons.

 

do it, i think those would look awesome. they're the first pair of angel eyes i've seen that actually look halfway decent as far as quality. FK is a decent brand as well, they don't make garbage. i love the look of angel eyes, who cares if they're a BMW thing. how are they rice? what about an M3 lip, is that rice? or lower fogs?

 

I agree with bent.. those look real nice you might wanna call FK to see what type of bulbs they use.

 

Will these fit on an S4 with stock HID system? Some people have told me yes some say no?

 

Save your money and get something else.
