They say hindsight is 20/20, and that`s probably never been more literal than now. Reduce blind spots, and get a wider angle of vision with this cool wide angle mirror. It has a slide that adjusts to all standard car, truck, SUV, and van mirrors. The flat glass surface reduces overlap vision, distortion, and reduces headlight glare. It adjusts as easily as a regular car mirror and wont get in the way of your visor. Seeing is believing. Measures 12" long.
