The main drawback to owning a minivan with one of these lightsaber wiper blades probably isn't the theft and vandalism, although you just know the blades would get stolen. Rather, it's the overwhelming urge to declare "I am your father!" every time you pick your child from school ... and from soccer practice ... and from friends' houses.
But, hey, what's a child's embarrassment compared to the enjoyment you experience as a Star Wars fan?
The blades are sold by WiperTags in a variety of colors, from Sith red to Jedi blue, green and purple, allowing you to change as the mood strikes you. Which will probably be pretty often -- and not only because the neighborhood kids keep stealing your lightsabers.
