Guys, Looked at my headlamp wipers, and the rubber is looking low and is kind of bent where they sit without moving for so long. Can you guys tell me: 1. How much rubber should I see on the blade. As much as a new Windscreen wiper blade or less? 2. Anyone ever bought these, or have any idea how to replace? The tiny wiper blade and arm looks one peice to me. EDIT: WHY? My car does not stay clean for half a week in the summer, I think I'm likely to give up washing in the winter and I want to take advantage of these!
