Now, a tinted halogen bulb, like a Silverstar is going to have a higher color temperature, closer to 4000K. Of course the more blue/purple you tint a bulb, the higher the color temperature will appear, but you'll also lose more and more of the actual output. Traditional non halogen, tungsten incandescents like you use in your house are 2700K or even a bit lower. If you're going < 30mph, then having HID bulbs in your fogs might help, but past that you're better off having a lower powered fog to assist a little with peripheral vision and have your brighter lights pointing down the road. If you like the look and they're aimed down where they should be and aren't bothering other drivers, then go for it. I'm not trying to stop anyone form doing what they want.
So basically youre saying use the fog lights for what they are meant to be used for...short distance light output, rather than going for bright, long distance output?
I just ordered a kit from DDM and am going to try the Hella yellows for foglights... Thanks for the links/info!
I think the 3K kit works well to show everything a 5K lowbeam misses. Just take the time to aim them right. I am very happy with mine.
