The relay harness redirects the power. So when you turn on your headlights, the ballast pulls power directly from the battery instead of having to go though the factory wiring of your car. And if your car did not come with hids from the factory, the wiring usually cannot handle the extra power going through the wires. Which could cause them to melt and possibly catch on fire in the worst cases. But even if your car came with hids and your just looking to upgrade or renew the kit. Getting a good relay harness is still better than factory wiring. The better the wiring to the hid ballast the brighter your headlights could be.

Is 6000K HID lights legal in California How about 8000K?

From what i understand, HID kits are illegal unless you have a projector installed on your car so it controls the light output of the HID's. Projectors spread the light evenly and have a cut off point which don't blind on coming drivers. Don't just install the hid kit, replace your headlights with projects =)
