I had 6000K for awhile. I liked the matching look with my headlights.
I eventually felt I just needed to change something, you know, just to switch it up and keep it fresh. So I moved to the 3000K JDM yellow fogs.
I have my old bulbs, I can switch them in with ease at any point. Realistically for like 50 bucks, its cool to be able to switch between either or. Like changing my kicks, or my hat. I do it by how I am feeling that day...
