Abstract: A reflective surface device that is detachably mountable to the exterior of a vehicle and method of making and using the same is provided. The reflective surface device has an arm having a proximal end and a distal end, a reflective surface disposed adjacent the distal end of the arm, and a magnet disposed adjacent the proximal end of the arm. In a method of using the reflective surface device, a user positions the magnet on an exterior surface of the vehicle with the reflective surface facing generally rearward of the vehicle, whereby magnetic forces between the magnet and the exterior surface of the vehicle support the reflective surface device on the vehicle. To detach the reflective surface device from the vehicle, the user applies a force to overcome the magnetic forces between the magnet and the exterior surface of the vehicle.
