Hella, KC, Lightforce are all good. PIAA are my preference for standard (non-LED) lighting.
If you want to spend an extra couple pennies to get the lighting you want without making your Subie look all kinds of rediculous, check out LED bars... Rigid Industries E-Series are great, check out their website and look at their gallery for what they look like and how holy-mother-of-God bright they are. I've heard good things about Baja Designs' offerings but I don't have any experience with them.
