There are only really 4 colours of HID available, despite the claim of sellers and manufacturers to the contrary. These are Standard factory 4300K (yellowish white), 5000K crystal white with no blue tint, 6000 crisp white light with delicate to moderate blue tint, and 8000K strong blue light. The highest light output is 4300K and the lowest 8000K. We have been driving with HID Headlights now for many years and as you may have guessed, have tested every combination of Kit, bulb and colour. 

 

The following is a summary of our findings (objective as we bought light meters to measure the actual light outputs) and recommendations (both objective and subjective), which most customers agree with 

 

8000K or higher are not the answer - they produce very little light – up to 70% less than the 4300K and the Police do not like them. Also the blue light is tiring on your eyes and will turn rear number plates Green! We generally recommend these for show purposes or for those that really want to stand out from the crowd. 

 

If you want the most amount of light on the road then I recommend the 5000K - which is a little whiter than the 4300K whilst having NO blue and very similar light output to the 4300K with our ballasts. For the purists we do have some 4300K bulbs also. 

 

One last thing about HID Headlights as proved in our testing, not all manufacturers colour ratings are same, so please dont try to compare! 

Some claims 12000K is sky blue!! Wrong - should be purple!!
