While driving on the road, it happens that somebodys headlights are excessively bright, creating an awful glare in your rear view mirror. This situation could be annoying for you and could be extremely dangerous. The GoSafe 260 comes with a mirror that automatically filters the extra bright beams of a car's headlights behind you. The mirror tends to have a darker grayish appearance than most stock rearview mirrors and you may need some time to get used to it, the benefit is that it detects bright light and automatically dims the reflection. Please note that objects in the mirror are closer than they appear. Enlarged mirror surface gives drivers better viewing angle of the rear.
