This disc lock insert stores inside the disc lock when not in use. When removed from the lock, a super bright blinking L.E.D is activated. Magnetic strips on the insert permit temporary mounting on your tank, Speedo bezel, or any magnetic metal surface.
The bright flashing L.E.D along with the large ARMED warning on it will trick the would-be thief into thinking you have an alarm, as well as remind you that your lock is still in place before you become the entertainment!
