I got the hid kit from interpower for $349 shipped. I got the 6000k kit which is just a tad bit more plasma like than factory lexus. The kit is F'n awesome. I pulled up next to a 350z and my lights are way brighhter but have not bothered other drivers. i also got brand new headlight housings ( highly recomended) for $75 shipped from new and used on ebay. E-mail me for pics brandon@purposefurniture.com. I higly reccomend this upgrade as it was fairly easy install and incredible anmount of lighting difference.
