hey everyone thanks for the postive feedback, i'm currently using the 6000k bulbs on my car at the moment, the corollas have a built in deflector thing so its not glaring, i'll take pics tonite so you can see the difference, installation is veryyyyy easy, like 10 minutes? 6000k is the way to go in terms of legality, of course if u use 8000k/10000k it takes one anal cop to defect you, hence my choice, the color is very white and you wont be disappointed, yes its made in china but for $250 you cant really ask for more, but it uses the same ballast and bulbs as 'AURA' the HID brand, its not philips or hella but you cant really tell a difference, the price is the same for h1, h7, h3? but h4 is more expensive. so it will not only fit corollas but other cars as well. ill post pics up later tonite, thanks! sorry forgot to add, its not advsiable to use HIDs as high beams, as kevin said takes too long to 'energise' but you can use them in fog lights too :)
