1, 2, 3, and 8 are easy to install..u dont have to be a mechanic to do them..ask a friend or someone to help you out..most of these products come with instructions, if not, you can search the forum..if you go get them installed, it would cost you around at least 20 bucks for each of 'em..4, 5, and 6, you may need to ask someone with experience so as not to mess up with the wirings..but again, they may come with instructions too..about the angel eyes, i remember someone posted a step by step on how to put them on, but i forgot which website was it..try searching this forum and other celica forums..goodluck!
