We are not sure how effective it is; just try this method when it rains heavily. This method was told by a Police friend who had experienced and confirmed it. It is useful, even driving at night.
Most of the motorists would turn on HIGH or FASTEST SPEED of the wipers during heavy downpour, yet the visibility in front of the windscreen is still bad.
Thus, in the event you face such situation, just try your SUN GLASSES (any model will do). All of a sudden, your visibility in front of your windscreen is perfectly clear, as if there is no rain.
Try it yourself.
Make sure you have a pair of SUN GLASSES in your car. You are not only helping yourself to drive safely with good vision, but also you might save your friend's life when driving in the rain.
Please tell all your friends!
I have tried it and it works.
Suggest you put on yellow glasses for brighter visibility for night driving.
