safest bet would be to use the 3000k as a fog light so it looks more natural...the suns kelvin temperature brightness runs at around 5770-5780k thats why most stock hid kits try to imitate the temperature of natural sunlight the closer you are the less you will gain attention from police. ive had a few different i ran 12000k on my gsr it looks good but just not very practical for vision. im currently running 8000k on my em1 and the sight difference is great. Due to temperature on the light spectrum the yellow will only lessen your vision at night. i am going to be running 3000k fogs though. Personally just love the lexus look coming at me.
