Traffic Light Viewer Deluxe Model with Chrome Arm. Don't tell me you don't remember this! You sure would if you have a sunvisor or chopped roof. The light refracts through the lens. It pivots and swivels. Remove one of the windshield trim screws and put it there or drill a small hole. Then you don't have to bend over un-naturally trying to see that light. Pretty embarrassing! Watching for somebody else to go first? We now also have the magnetic base in stock.
