Do you know?
Try to check our your car's rear mirror now, maybe you are not realize, there is a button at the bottom of the mirror. You might wonder what is the function when we switch the button down or up? Some of you might say, that is for different height driver adjust to suit within a car. NO, that is wrong. Look at the photo I had shot for you, before and after. Can you differentiate it? " Before ", the behind car's light is brighter than the " after ". That is the way to use. Sometimes when we are driving at night, car's headlight / spotlight at behind might straight to your eyes and feel very uncomfortable, because it is too bright. Try to adjust to button down / up, the brightness will be reduced about 70%! Amazing?
