I have saw these before on people's tractors. Looks to be thick plastic? Color coded to tractor make! With info on the tractor, and owner. Where can you get these? I have searched with no luck!

Google = engraved plastic signs. Also most big tractor shows have a vendor that makes them while you wait.

Most area sign shops make them. Just give them a diagram of what you want, and the colors.
