I definitly recommend the HID kit upgrade. I have MTEC 4500K, and they look completly factory. Factory HID's will range anywhere from around 4300 to 4900K. When you go above 5000K, you loose intensity. As for the brights, it is POINTLESS. HID's have to warm up. it takes up to 1 minute for HID's to achieve maximum brightness, so when you first turn on the brights, the will be less bright than the bulbs. Also, if you have used your brights, why would you need them any brighter? they are a directional beam that points straight ahead. Unless you drive down a long country road at night with your brights on, there is definitly no need to put HID's in the brights. TIP: BUY A QUALITY SET OF HID's.
