I am thinking about changing my fog lights to either 3000K HID Conversion kit or just some 20 bucks Super Yellow Halogen bulbs.
I have seen them side by side before and somehow I think those super yellow halogen bulbs appear much yellower than the 3000K HID Conversion Kit, so is the HID kit really worth the investment?

 

Get whichever one is cheaper. For function, there is no need for HIDs in the fogs unless you just want to be blinding people.
