I spoke to someone on carid.com and they said i need to purchase 2 packs of the H7 bulb for high and low beams...wouldnt the bulb look the same if i turn my brights on?

 

highs a lows are the same bulb.

doing a HID kit is not really a practical idea for these rigs. i would recommend a good set of bulbs like PIAA etc

 

I like my HID's. I have them in the fog lights low, high beams and driving lights. It really makes a difference. Here is my writeup. I bought mine at HIDExtra.com The leader in Xenon HID conversion kits. Both high and low beams are H7, you need two separate kits. Fog lights are H3 if I remember correctly. Go with 4000k kelvins bulb temp for the brighest white closest to day light.
Even some of the eBay kits are OK from Xtream hids. If you take a close look all the wireing is from the same place in China.

 

Unless you change the headlight housing too HID kits are illegal.
