If you put on a light like that it'll require cutting off the windscreen/headlight mount bracket. That means you can't go back if you don't like it, and unless you fab something up, you won't have a windscreen.
If that doesn't sound like something you want, you can always install an HID kit into the stock headlight housing. Some of them look pretty good; there's a thread about it floating around here somewhere.
