I've seen a guy around town in a lowered older chevy pick up with 12k. It looks a little ridiculous using them as headlights, and I look at the light output everytime and it looks like it would do some crazy things to your eyes. I think 12k would be neat as fog lights though. I have 5k and they're really white, almost blue, but I like them.

 

Ya sort of...

Crazy how much this site has changed, the once Noobs are now Mods... LOL

this has a chart of the spectrum on it. Its from the halo's im gonna get eventually
I like the 8000k the best personally
6000k is pure white and 8000k has a nice slightly blue tint

 

6000k already has a blue tint and 8000k has far too much for optimal vision.

 

6000k is pretty white when you first install it but it'll turn bluish after some use. 4300k or 5000k is the closest to white any company makes
