Walked around my car today and noticed a dime-sized hole in my right side view mirror turn signal lens

. Have no memory of getting it... haven't even drafted off any trucks in a while! I know it wasn't there at my last car wash (a week or so ago). Guess I'll need to get a replacement lens and get to work... don't want dirt and water to get into the electronics within the mirror. Guessing it'll be a small fortune to get the lens (I'll do my own labor).
Be sure to inspect your lenses from time to time. They're obviously targets for road debris!
