opt7 kit off of amazon. I've installed a lot of kits and they are the best I've ever installed. comes with everything you would need and is cheap!! customer support is awsome too. my only advice is to get a 35 watt kit so you don't completely blind everyone and possibly adjust the beams down.
I went down to my car audio place in Seattle and bought my HIDs there they cost me $100 for the low set of 8000 K's. Trust me you don't need high beams with HIDs so don't let anybody talk you into buying the highs because it's a lot more money. But mine are The Bluest headlights on the road and you can see for miles but it was a pain in the ass installing them because I had to put another light in there as a relay I think it was just to make my HIDs work. But it was well worth it. I would definitely check out Ebay they have all kinds of hid sets for good prices. Maybe if you don't buy pink ones you could buy pink lighting and install them inside your headlight casing and just have a switch for it. That's what my buddy did on his Jeep with red LEDs and it looks killer.
