It’s a Good Idea to Use the Rearview Mirror Tab to Avoid being Dazzled.
When someone uses their bright lights to blind you in your rearview mirror, it could be annoying. You may use the tab on the back of the mirror to limit the effect of the bright lights. To lower the mirror, merely push down on the tab on the rear of the mirror.
After that, you won’t have any problems with your vision since the light will reflect in the other direction, down. If you have a manual tilt version of the gadget, switching the mirror between its day and night settings is a simple process.
