Any HID kit will provide a cleaner and significantly brighter output than the stock bulbs in your headlights. But price varies depending on the quality and HID kits, like these guys have stated, can range anywhere from $80 from an eBay vendor to $200 for a quality HID kit. It's like you said, you gotta pay for quality. Now, the Lexus/BMW/Benz blue-ish light color that you're talking about would be in the 6000K to 8000K heat range. The higher up the Kelvin rating scale you go, the more blue the light will be(10,000K for example, will be deep blue,almost violet). So if you wanted a balance between the high-end vehicles'(Lexus/BMW/Benz) blue light and a bright, white light(brighter than stock) then I would suggest going for 8000K HIDs. I dont know much about the wiring stuff, but from what I can understand some HID kits just plug into the stock wiring. This is a quote from the website that DBoy linked to in the above post:Originally Posted by massivesystem
"Motorcycles and automobiles currently use a 12 Volt electrical system for their headlamps. XENON HID lighting systems require over 20,000 volts to ignite the bulbs. Once lit, they only require 85 volts to keep running. Our kits include a power pack that is necessary for the lamps to turn on. The input of the power pack is 9-16 volts. It is an integral part of the system. You DO NOT require any additional components to install the XENON HID lamp into the original socket of the halogen bulb. This is a plug & play unit. Simply replace your factory bulbs with Our Xenon bulbs, plug the bulb to the ballast, and the ballast plugs to the factory OEM harness. No cutting, rewiring, or any other modifications needed. "
I hope I haven't confused you any more, but I would suggest talking to BackinBlack, he's an electrical guru and could answer any questions you need to know about wiring up HIDs
