I bought HID's this week and put them installed them today. I specified H4 6,000k bulbs. I have OEM Xenon on my other cars and these are every bit as bright if not more so. After having Xenon on my other cars for the past six years, I could barely see the road when I bought my Crossfire a month ago. This kit has nice mounting brackets that are rubber mounted and excellent water proof connections. I have absolutely no radio interference or any other unwanted side effects. They are just like my OEM Xenon's in my other cars except the don't do the little dance when you first turn them on. The only problems I encountered was not know which wire on the original connection was negative... (It is the one with two wires) and messing with the clip on the first light. The first light took over an hour and second one was about 10 minutes. The kit arrived very quickly and a total shipped cost of only $75.98! The link below is what I went with:
