Andi - it is a $50 added cost to the regular yearly fee, in California anyway. Other options than black or white available but cost more and supports various causes, fire fighters, environment, etc.

Had to wait till my senior years to get the car though. In reality rear fog lights are unknown here. Even though we get a fair amount of fog here in northern California. People here only know of front fog lights. But you make a good point. The GBS chassis loom places the fog light on the right side and not looking for more work to do will probably just leave it alone. Will probably never remember to use it anyway, and other drivers would just think I'm riding my brakes anyway.

Will send it to anyone privately that is interested but it does need editing.
Every state has different laws and requirements for car registration. I only have experienced California which I think is one of the worst. So the same plate could be issues by another state if they offer that option. Here is what my other kit car has;
