I recently bought a HID conversion kit for my 05 SV6....well worth the 32 dollars I spent. Get on Ebay, look up a company called Xentec. The come with a 1 year replacement warranty on all the parts they send. It's a plug and play system that is super easy to install. The hardest part of the install was removing the headlight assembly to access the bulbs. That would be my suggestion, just beware if you have a single bulb system, it will cost you 62 for their "dual beam" HID kit. I bought the 8k kit, and I LOVE IT
