Abstract
An improved wiper blade of the type used on a vehicle windshield having an indicator means painted on the wiper blade which indicates that the wiper blade should be replaced. The exposure to UV light of the indicator painted on the wiper blade causes it to change in color and thus communicate to the user that it is time to change. The indicator paint is a silicone resin paint and would be applied to a wiper blade made of a resilient elastomeric material which is degraded with exposure to UV light in the atmosphere.
