We did a little comparison in Gainesvile 2 weeks ago, and some Walmart Super Blue/White Bulbs ended up being brighter and cleaner lookign than the PIAA...go figure. Also, you can put the 9005's in both your lows and his if you file down the plug...that will make a big difference on your illumination, as well as the fact you can go all the way up to 100 watt bulbs inyour fogs.
