I am getting ready to purchase HID conversion kits for all lights (high/low & fog). I am looking the jetttstream set. For the low beams I know I need the drl module and relay harness. What do I need for the high beams and fog lamps? Also, the higher the number (ex 15,000K) does it give you more light or is just the color. I want the brightest light possible. The color does not bother me. Thanks.
