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?

 

The HiD kit will be brighter and not very yellow. The more color coating on a bulb, the less bright it will be. To see HiD color chart, click here: HID color chart | Xenon colour chart
