i was going to get the single beam hid's but for 20 bucks more (including shipping 90 bucks total) i got the bi xenon hid's and there supposed to be bright as hell. If you get single beam hid's and if you turn your fog lights on the high beam light on the cluster will light up because of the power going through the stock harness so i got the bi xenon's. Its a whole kit including ballast's the bulbs the power cable the ignitors the hardware and the relay harness . Its not as complicated as it seems to be. Here's a tutorial for you. http://www.vvme.com/page.html?chapter=3&id=21
