I am looking at buying the HID kit for my car off of ebay. But it says Certain cars might require a relay harness and or canceller, sold separately. Does a 2007 Aveo need this relay harness? Also I have read that some HID's will melt my lens? Is this kit a good one? Xentec HID Kit Slim Xenon 9003 H4 Hi Lo 10000K Deep Blue Beam Conversion Light | eBay
