I am sharing my experience with HID kit. I wanted a High Intensity Discharge kit for my 85 Cadillac Cimarron which is a very cool light and better visibility especially during night driving. I opted to go with the single beam HID kit too and love it, they are cheaper on ebay but I wanted a warranty so I got it here Sealed Beam Headlight Kits or you can try one of the vendors. Also some of the forum sponsors usually have a sale going on. Either way its a great system, and very easy to install.
