Claim 6:
7. A cylindrical lock comprising:
a latch moveable between an engaged position operable to limit ingress and egress and a disengaged position not operable to limit ingress and egress;
an egress actuator operable to receive a first operator input motion to actuate the egress actuator to move the latch from the engaged position to the disengaged position;
an ingress actuator operable to receive a second operator input motion to actuate the ingress actuator to move the latch from the engaged position to the disengaged position;
a lock input actuatable between a locked position and an unlocked position, the locked position of the lock input positioning the lock in a locked condition blocking the first and second the latch from moving from the engaged position to the disengaged position;
a first indicator having a lock signal signaling the locked position of the lock input and an unlock signal signaling the unlocked position of the lock input, the first indicator selectively displaying only one of the lock signal and the unlock signal, the first indicator having a lock signal display position in which the lock signal is displayed and an unlock signal display position in which the unlock signal is displayed;
a second indicator having a lock signal signaling the locked position of the lock input and an unlock signal signaling the unlocked position of the lock input, the second indicator selectively displaying only one of the lock signal and the unlock signal, the second indicator having a lock signal display position in which the lock signal is displayed and an unlock signal display position in which the unlock signal is displayed, the second indicator and the first indicator positioned about a first longitudinal axis; and
a transmission rod operably coupling the first and second indicators such that when the first indicator displays the lock signal the second indicator displays the lock signal and such that when the first indicator displays the unlock signal the second indicator displays the unlock signal, the transmission rod having a second longitudinal axis spaced apart from the first longitudinal axis.
