im going to be buying a set of HIDs off ebay and im not quite sure on what color temp to get im debating between 6000k or 8000k now are these simmilar enough not to notice any real difference between the visable light output? also ive read that getting some sort of a relay is a good idea and if so where would i be able to find one and wat would it even look like??

 

well, you need a relay, they are just a switch. HIDs are lower wattage, but higher amperage. you dont use the wires from your stock head lights to power your HIDS, you use a relay to use power right off your battery. there is lots of info on how to properly hook them up.
