Color Temperature

The color temperature 3000k is golden yellow, most suitable for fog lights. The higher the temperature the more blue is in the color of the bulb. Maximum light output is around the 4000k-4500k (OEM kits are around 4100k-4300k) temperature, so if you are going for maximum brightness we recommend the 5000k kit. The higher the kelvin temperature (k) the deeper the blue color of the light will be.
