Hi, I have a 2004 GMC Sierra 1500 Ext. Cab and I just got new Philips Crystal Vision Ultra Low Beam 4000K(9006) and High Beams 4000K(9005). I figured my lights were getting a little dim and I wanted to buy some more "whiter" lights rather than the yellow. They look good but does anyone know what kind of fog light I can get that will match the color of my headlights? It just looks ugly with white headlights and yellow fog lights. Any Ideas?

Thanks.
