I am extremely new to this site and just got a 2002 envoy about 4 months ago. This site has been extremely helpful in many ways and i appreciate you guys for that.:thumbsup: But I am thinking about putting a HID kit in my envoy but have no idea what i am looking for. I am planning on getting either a 6-8000k kit, but is that just the low beam? Is it necessary to buy it with a high beam function as well? Any help/advice would be extremely helpful.:thx
