Having trouble with blind spots" CIPA's Panoramic Clip-On Style Rearview Mirror will help you solve the problem. Its convex design and 11.5 x 2 inch viewing area helps to drastically reduce blind spots, deflect glare, and expand your overall field of view. The glass in Panoramic Clip-On Style Rearview Mirror features a slight amber tint to help with glare reduction. Reflections also appear clearer, brighter, with vibrant color, and with greater detail. With a total length of 11.75 inches and rounded corners, most visors will be unobstructed, but will vary between different makes and models. The Panoramic Clip-On Style Rearview mirror is easy to install over your factory rearview mirror with its spring loaded clips that are located on the back. The clips will mount to most factory mirrors tightly and securely - eliminating any noise or annoying vibration. Once installed, you can adjust the direction of the mirror by positioning your factory rearview mirror as usual. Rubber coating on the clips ensure your factory mirror will not get scratched or marred with the use of this product. The mounting clips extend as far as 3 inches from top to bottom. Vehicles with rearview mirrors that contain integrated controls such as OnStar, or digital displays for compass/temperature may not be compatible due to height. The mirror might also interfere with the use of dual map lights, but can easily be removed and remounted in seconds without the need for any tools. The quick mount system is also great for transferring the mirror from vehicle to vehicle. Warning: due to its convex design, objects in this mirror may be closer than they appear.
