EV Wheel Coin or Horn Button

This wheel coin adorns my all electric GT-40 replica. The wheels were originally from a late model Camero that had plastic hub caps. Originally these caps had a coin with the Chevy logo on them.

If you have and electric car and want to identify it as an EV, this is a nice little piece.

See the below link for images of its use.
