stick with 6000K the most for safety. Cause when u go over 6000K like say 8000K, it'll be less light output, ull have trouble especially during rainy weather, snow. And, the 8000K looks like jdm blue halogen wannabe xenons. I think the 6000K looks great, got a lil bit of a blue tint on it from far, and it's still blue/white when u get close to it. The 4300K got a blue hue from far, but when u get close, it looks kindda white/yellowish. But it puts out the most light.
