The main difference is the brightness and color temperature of them. I personally have the Cool Blue bright bulbs in my Bright socket, and Silverstar bright bulbs in the Normal socket. The result? Headlights that are bright as hell, and me having to pay more attention to when there is oncomming traffic when I have my brights on! lol. -Nick
