Yes, you can be pulled over for them. HID Kits are 100% illegal for road use on a vehicle that did not come equipped with them from the vehicle manufacturer. This includes retrofitting a factory HID Kit from another car to yours. With that being said, anything that is closer to white will almost be perfectly safe from police. As you detour from that and add more color, your risk will go up and you could receive a ticket. I know one person that got a ticket for 8000k by a Gwinnett County cop...which is barely above a stock BMW. In the end, it just depends on the cop you come across. Some could care less, some that is their pet peeve.
