I have a 10000k kit that i got for 200 dollars that i love. I have a buddy with an 8000k kit that he got for 190 bucks. Next to eachother you cant tell the least bit difference. from about a quarter mile or half mile away mine have a little bit bluer tint but theres no purple and its not any brighter. For some reason when people hear 10000k they think itll be straight purple but mine a re barely blue. For the money we spent, we can't imagine having cobras without them, its one of the best visual upgrades you can get, even for 300 dollars, id suggest it to everyone. As far as the color goes, either 8000k or 10000k is fine and you wont be able to tell much difference. Just keep in mind that if your lenses are the least bit dirty, either clean them or get new ones cause the hids bring out every bit of fog.
