What 4300k kit have you bought in the past? All the 4300k kits I've installed lit up blue, but end up pure white. The 5000k bulbs I just purchased for my CM shine blue, which is not much brighter than my stock halogens (as far as road illumination).If you want no blue but a whiter light go with 5000K with 35w ballasts. 4300K will give you a tinge of yellow, but still ultra white in comparison to halogen bulbs.
Had two sets of those on my old Armada. Both sets lasted about under 2 months. Didn't have the relay harness back then. Xentec ballasts do NOT like flickering at all (lesson learned).
Lol, I forgot to add that on my post. Xentec sucks imo!!!! I think my kit lasted 3no, I just wanted to point out how it depends on which brand u get to know what # u need to get the color u need
