i was surfing online and came across this lexus forum. i was so shocked! a pic of my car is posted so i decided to register and share my happiness. i have a 2003 LX470 and the H1 low beam output is just poor! i had a 1999 LX470 and they were poor as well. so, i upgraded with CATZ 4500K HID kit. it's AWESOME! SO HOT!!!! i get ALOT of compliments from people in the parking lot and get alot of stares and turning heads. not everday you see a LX470 with HIDs! haha. :D in seriousness, HIDs makes driving at night a whole new experience. the CATZ HID kit is excellent quality. JDM! i recommend http://www.liteswap.com . that's where i purchsed my kit, awesome customer service. i have installed 3 of their HID kits thus far and have no problems whatsoever with them so far and very pleased with each of them. Mercedes S-class, LX470 and Prelude. ;)
