to be honest, all HIDs are the same. you get what you pay for. If you wat cheap but failry decent, i would go ebay and look. if you have money to blow go with EUROLIGHTS, Pro Lumen, McCulloch are like high end

well nice colours are 5000k - 10000 k

5k is pure white
6k white with tint of blue
popular one i install most are 8000k. 10 000 cops might be an asshole and give you a ticket
