A fantastic wiper blade is one of the most important things for safe driving. Most vehicles these days are fitted with wiperblades, what is good for one vehicle is good for all. J. H. Apjohn an american was the inventor of the original wiperblade. The ‘swinging arm’ blade was also invented in the same year by an American lady called Mary Anderson. In order for there to be good visibility a combination of using the wiperblade to clear dust and debris from the screen and fluid is used. You have a choice when choosing what fluid you put in the water pump, water is cheaper but wiper fluid does not freeze as easily. With the advances in technology eventually wiperblades were added to the rear windows and also to the haedlights in many cars. Many modern cars now have rain sensors added to the wiperblades so they activate once the rain starts.
