Hella Optilux are good ones, and not just because the Angel Eyes look cool, but the driving lights are incredibly bright and shoot a nice long white path of light. The visibilty of the fogs/driving lights over stock is worth the conversion alone. They are also glass, not plastic that pit easily like the stock fogs. And they aren't expensive at all. The angel eyes are just for looks.
Keep the receipt of the Hellas if you get them, some people have had an LED blow out early and the rings are then not as bright. I got a set that did that and the store replaced them for me.
