Viral List Builder

I have been looking for info online but haven’t found much. Dont just throw out the basic turn signals, head lights, ect ect… if you dont really know. We are going to build a car from scratch and are still in the design phase and need to know EVERYTHING that is needed not one or two things that people can think of. If you know of a website or other resource that has such info then you can provide a link and thats really all I will need. Also if you make a list please list your resources so I know that it is accurate. If you just happen to have built a street legal from scratch then ill be glad on any input you can give me about making it street legal. Sorry if i sound rude to the knowledgeable people out there, I just don’t want people to give me what they think or believe I will need when they really have no clue. Just remember its not a production car and the laws to make it road worthy are going to be much different, For the most part I wont need as much, but I have to know what..
