I did 6k LED's for both my low and high beams. I am not planning to change my fog lamps. Some have posted that the higher the temp of the color the less the do in fog and heavy rain. So leaving the fogs alone gives me some safety border, I think. Plus replacing the fog lamps is a lot more mechanical and I am not mechanically inclined.

 

H16 fog light bulbs



The cheap alternatives are halogen bulbs (H16 19W) but they usually don't last long.

 

@lok888 - Enjoy your new HID kit.

What are you looking to achieve by changing out the stock fog bulbs?

I remember something about that, as the white light maybe reflectingbounng nd in the fog? Maybe yellow bounces less?

We have a thread on it with links to some testing, I forgot the outcome.

..and why they have yellow fog, or filters..... very easy to ask for yellow filters to add. Some LED fog sellers have this as an added option.
Maybe Steve from XD can comment

 

I believe that yellow light is *supposed* to be better in fog applications because the yellow light doesn't prism off the water particles in the fog. I say supposed because I think I read a while ago that this theory was proven false.

However, from personal experience I believe that warmer tones in fog lights do function better when driving in the snow/rain.
