These are the side view mirrors that expand a driver’s field of vision 2 1/2X to easily see a car’s blind spots. They firmly clamp to a vehicle’s existing side mirrors using the included hardware without any drilling, enabling motorists to comfortably monitor an extra lane of traffic and the immediate areas around a car’s doors without turning or craning. The convex surface of the mirrors’ German-produced optic glass reduces glare, and their angle provides a full view of the ground and curb for painless parallel parking. Set of two. 5 3/4" L x 2 1/2" H x 2 1/8" D. (8 oz.)
