Power Vision Mirrors are the only available electrically extending mirrors on the market. Reach an overall width of 109 to 112 inches (depending on model) with the touch of a button. Conveniently extend your mirrors for towing, increasing rear visibility and safety. The large 6.5-by-10.5 inch flat glass surface provides a true field of vision and prevents image distortion. The mirrors fold on impact, both to the front and rear, protecting your door and allowing you to get into close quarters. Power Vision Mirrors are available with heat and turn signal options.
