I bought a set of LED headlights off of eBay.

They were cheap, at around $30/sealed housing. They plugged right in and worked without any kind of anti-flicker harness or load resistor required. If they go kaput after less than a year, I'll step up to a more genuine HID kit, or higher quality LEDs.
I am having good luck with the same type of cheapo LED headlights on my Datsun. Don't drive at night much, but I've had the lights for almost 3 years and they have been great.
