I talked about this on another site, I am after a Corvette look.
I think I am going to make something like what you see on that 53 Corvette to mount right at the rail like this.
The third brake light, I don't know, I don't want it to be seen but when it's on, I would love to pull that off! But it will likely be in the rear window? I don't know, we will see.
