Well it really depends what you want. Do you want a 3 in. Or 2 1/2 in lens? Do you want halogen like stock ducs, or hid? Do you want bi-xenon " high beam is actuated with a solenoid" therefore not needing a sepearate high beam bulb.
Are you trying to retrofit something into the existing housing, or do it like the pic? Well you could go the cheap way by getting something off of eBay which is what the projector in the pic looks like, or you could check out the retrofit source for possible options such as tsx, rx 330, E46 or E55 projectors, plus many more.
Acura or Lexus should have them. In fact, the older 90's Lexus have good ones. But if you want something really trick and high end, consider looking at the driving lights made by PIAA and Hella. They are quality lights believe it or not, many manufacturers such as BMW, Porsche have their lights made by these 3rd parties.
