Steps 5 and 6 are needle selection and trim selection. There are three needle styles-Modern, Classic, and Vintage-in the full range of colors. The trim rings come in black (which can be painted any color), chrome, or gold. For our design, Aaron chose the Classic-style needle in an amber color, and the chrome trim ring. Step 7 is Finish. Your gauge design is converted to a PDF file and uploaded to the Aurora site. From there, the company prints your gauge face and ships it to you.
