A pipeline pig signal includes sealing means located within a lower end of the trigger cavity of the signal which prevents pipeline debris from entering the trigger cavity. The sealing means moves between a first sealing position and a second sealing position in response to the trigger moving between a non-triggered and triggered position. The sealing means may be a polymer boot, a filter arrangement, a sliding piston arrangement, or a sliding shelf arrangement.
