A method for providing a visual expiration indication for a surgical instrument includes holding an indicator body in a first position with a detent mechanism to provide a visual in-service indication for the surgical instrument. The indicator body is engaged with a motor and the indicator body is rotated with the motor from the first position to a second position that provides a visual expired indication. The indicator body is prevented from rotating from the second position to the first position with the detent mechanism. The detent mechanism may hold the indicator body in one of only two positions. The visual indications may be displayed through an aperture fixed to the base of the surgical instrument. The indicator body may be elastically deformed when the indicator body is rotated from the first position to the second position. The motor may be rotated to gain momentum before rotating the indicator body.
