I found these years ago and was going to use them on my dads pickup but need to let them go. Often called cats eyes, one is a cigarette lighter and the other a map light. They both appear unused. Great art deco pieces to add to a period correct dash. I have not tried to power up either piece. One knob is green and the other red, they are interchangeable. Price is $85.00 shipped to lower 48 states.
